[0002] Due to its characteristics of high brightness, high directionality, high monochromaticity, and high coherence, laser has a wide range of applications in fields such as information, processing, medicine, and military.

[0003] Traditional laser control methods are often simple and fixed, typically operating in only a single mode and lacking the ability to flexibly adjust parameters according to different application scenarios and user needs. In the past, laser operating modes may have required manual switching, and during operation, it was difficult to adjust output parameters (such as current, duty cycle, amplitude, etc.) in real time according to actual working conditions. Even if some lasers could be adjusted to a certain extent, they often lacked precise feedback mechanisms, making it impossible to accurately determine the deviation between the actual and expected outputs, let alone achieve automatic adjustment of deviations.

[0004] At the same time, the lack of an intelligent matching mechanism makes it difficult to find the optimal parameter combination quickly and accurately for different desired parameters, resulting in the laser's performance not being fully utilized and limiting its effectiveness and efficiency in various complex application scenarios.

[0021] Please see Figure 1 As shown, this embodiment provides a laser parameter intelligent control device, including a light source output module 1, a light source detection module 2, and a controller 4 connected together; Among them, the light source output module 1 is used to output a laser beam, and the light source detection module 2 is used to obtain the actual beam information from the received laser beam and transmit the actual beam information to the controller 4. The controller 4 is used to filter data according to the user's input desired parameters, and transmits the working mode signal and power parameter signal formed based on the filtering results to the power supply module 3. The power supply module 3 is used to provide power to the light source output module 1 according to the working mode signal and power parameter signal of the controller 4. The working mode signal includes CW mode or QCW mode, and the power parameter signal includes a first current value or a first parameter group. The first parameter group includes a second current value, duty cycle and amplitude. The controller 4 is also used to compare the received actual beam information with the desired parameters, and make parameter adjustment or mode switching decisions based on the comparison results to form an adjustment signal and transmit it to the power supply module 3. The power supply module 3 adjusts the power output according to the adjustment signal.

[0022] Specifically, in this embodiment, the light source output module 1 is one of the core components of the entire system. Its main task is to output a laser beam, which is the final output of the entire device. Its performance and characteristics are controlled and adjusted by the subsequent modules. Simultaneously, this module feeds back its operating status information to the controller 4. This operating status information reflects various conditions of the light source output module 1 during operation, such as the module's temperature and internal operating status indicators (e.g., whether it is operating normally, whether there are any abnormalities), providing a basis for monitoring and adjusting the entire system.

[0023] The light source detection module 2, comprising a power meter and a frequency meter, is a key component for measuring laser beam information. The power meter measures the power of the laser beam, providing crucial data support for subsequent parameter adjustments and system evaluation. For example, real-time power monitoring allows determination of whether the laser has reached the desired output power level and its stability. The frequency meter measures the frequency of the laser beam. Different applications may have varying frequency requirements; frequency measurement ensures that the output laser frequency meets these needs. This module transmits the measured actual beam information (including but not limited to average power and pulse width) to the controller 4. This actual beam information is essential for evaluating laser performance and determining whether parameter adjustments are necessary, serving as the fundamental data source for system feedback control.

[0024] The power supply module 3 outputs power to the light source output module 1 according to the working mode signal and power parameter signal sent by the controller 4. The working mode signal includes CW (continuous wave) mode or QCW (quasi-continuous wave) mode, and the power parameter signal includes a first current value or a first parameter group, wherein the first parameter group includes information such as a second current value, duty cycle and amplitude.

[0025] This method of adjusting the power output based on the signal from controller 4 allows power supply module 3 to flexibly provide suitable power support for different operating modes and different desired performance indicators. For example, in CW mode, the light source output module 1 provides a stable continuous current based on the first current value provided by controller 4, ensuring that the laser operates normally in continuous wave mode; in QCW mode, the power output is adjusted based on parameters such as the second current value, duty cycle, and amplitude to achieve quasi-continuous wave output characteristics.

[0026] The light source output module 1 can feed back its own operating status information to the controller 4. The controller 4 compares this information with the desired parameters and dynamically adjusts the power supply parameters based on the comparison results. This ensures the stability and performance optimization of the laser's operating status, exhibiting good adaptability and flexibility. It can adjust system parameters in a timely manner according to actual conditions, keeping the laser in its optimal operating state. The light source detection module 2 can acquire various actual beam information, including average power and pulse width, providing multi-dimensional data support for precise system control and performance evaluation. This facilitates accurate understanding and control of laser performance and can meet the parameter adjustment requirements of different operating modes, including CW and QCW modes.

[0027] The laser parameter intelligent control device described in this embodiment solves the problem of single laser mode, realizes intelligent switching of laser working mode, and improves the matching of peak power, pulse width, average power and user needs; at the same time, it improves the intelligence and integration level of laser parameter control, enhances the stability and performance of the system, and has certain innovative and practical value.

[0028] In some embodiments, the controller 4 includes an input module 41 and a data processing module 42, with the input module 41 and the data processing module 42 being communicatively connected. The input module 41 is used to acquire the expected parameters input by the user and transmit the expected parameters to the data processing module 42; wherein, the expected parameters include at least the expected peak power, the expected average power and the expected pulse width; Data processing module 42 includes data processing module 421 (corresponding to Figure 1 The FPGA shown) and control module 422 (corresponding to Figure 1 The MCU shown has a neural network model 4211 configured in the data processing module 421. The neural network model 4211 stores multiple current values ​​in CW mode and their corresponding standard beam information, as well as multiple parameter groups in QCW mode and their corresponding standard beam information. The control module 422 is equipped with a control system, which is used to select the first current value corresponding to the CW mode or the first parameter group corresponding to the QCW mode that meets the desired parameters from the neural network model 4211 according to the desired parameters.

[0029] Specifically, in this embodiment, the input module 41 and the data processing module 421 are connected synchronously to ensure timely and accurate information transmission. The input module 41 is primarily responsible for acquiring the desired parameters input by the user. These desired parameters are set by the user according to specific application requirements, including but not limited to desired peak power, desired average power, and desired pulse width. Users can input desired laser performance indicators according to different application scenarios to set targets for system operation. The input module 41 transmits these desired parameters to the data processing module 421 as the basis for subsequent control and adjustment.

[0030] The data processing module 421 includes an FPGA and an MCU, with the FPGA being the core processing unit of the entire controller 4. The FPGA carries a neural network model 4211, which stores various current values ​​and their corresponding standard beam information in CW mode, as well as various parameter sets and their corresponding standard beam information in QCW mode. This storage method allows the system to make decisions based on past experience data (i.e., the stored standard beam information). The neural network model 4211 has unique advantages in handling complex data relationships and pattern recognition; it can quickly find matching current values ​​or parameter sets for different desired parameters using the stored information. For example, under different desired peak power, desired average power, and desired pulse width, the system can use the neural network model 4211 to find the best-matching CW mode current value or QCW mode parameter set in a large amount of historical data, providing a basis for subsequent power supply and output control.

[0031] Furthermore, the FPGA in the data processing module 42 carries a neural network model 4211, which stores various parameter information in CW mode and QCW mode. Based on the user's input of expected parameters, the model can be used to filter out the first current value in CW mode or the first parameter group in QCW mode that meets the expectations, thereby realizing the intelligent parameter filtering function and improving the accuracy and rationality of parameter selection.

[0032] The MCU houses the control system, which serves as the execution and decision-making unit for the entire controller 4. Based on the input desired parameters, the MCU filters the neural network model 4211 to select the first current value corresponding to the CW mode or the first parameter set corresponding to the QCW mode that meets the desired parameters. The filtering results are then transmitted to the power supply module 3 as a working mode signal and power parameter signal, controlling the power supply module 3 to provide the corresponding power to the light source output module 1. Furthermore, the MCU receives the working status information from the light source output module 1 and the actual beam information from the light source detection module 2, compares the actual beam information with the desired parameters, and makes parameter adjustment or mode switching decisions based on the comparison results. These adjustments are then transmitted to the power supply module 3, prompting it to adjust the power supply.

[0033] In some implementations, the data processing module 421 includes an optimal current value selection unit, which is electrically connected to the control module 422. The optimal current value selection unit is used to calculate the percentage deviation between the standard beam information and the desired parameters in CW mode. The control module 422 selects the first current value with the smallest percentage deviation as the optimal current value. The control module 422 is used to transmit the optimal current value information to the power supply module 3 as a power parameter signal.

[0034] Specifically, in this embodiment, the optimal current value selection unit is used to select the optimal current value from N first current values ​​in CW mode and transmit it to the power supply module 3; wherein, N≥1; if N is 1, the first current value is directly transmitted to the MCU as the optimal current value; if N is greater than 1, the optimal current value selection unit calculates the percentage deviation I between the peak power An and the expected peak power in the standard beam information (including peak power An (An can be 0), average power Bn, and pulse width Cn) corresponding to the N sets of first current values; calculates the percentage deviation J between the average power Bn and the expected average power in the standard beam information; calculates the percentage deviation K between the pulse width Cn and the expected pulse width in the standard beam information; and transmits the calculation results to the MCU, which selects the first current value corresponding to the standard beam information with the smallest (I+J+K) as the optimal current value. Furthermore, the optimal current value selection unit is part of the FPGA and plays a crucial role in CW mode. When N initial current values ​​exist, it filters for the optimal current value. If N is 1, the value is directly given to the MCU; if N is greater than 1, it calculates the percentage deviations I, J, and K between each standard beam information (including peak power An, average power Bn, and pulse width Cn) and the desired parameters. Based on these percentage deviations, it transmits the results to the MCU, which selects the initial current value with the smallest (I+J+K) as the optimal value. Finally, this information is transmitted to the power supply module 3 as a power parameter signal.

[0035] In this embodiment, the unit ensures that the laser can obtain the optimal operating current in CW mode. By comprehensively considering the deviations between multiple beam information and desired parameters, the current value that best matches the desired performance is selected, thereby improving system performance and output laser quality. It can handle different numbers of initial current values ​​and flexibly process them according to different situations, ensuring that the system can find a suitable current under different initial conditions, thus enhancing the system's adaptability and stability.

[0036] In some embodiments, the data processing module 421 further includes an optimal parameter group selection unit, which is electrically connected to the control module 422. The optimal parameter group selection unit is used to calculate the percentage deviation between the standard beam information and the desired parameters in QCW mode. The control module 422 selects the first parameter group with the smallest percentage deviation as the optimal parameter group. The control module 422 is used to transmit the optimal parameter group information to the power supply module 3 as a power parameter signal.

[0037] Specifically, in this embodiment, the optimal parameter group selection unit is used to select the optimal parameter group from M first parameter groups in QCW mode and transmit it to the power supply module 3; wherein, M≥1; if M is 1, the first parameter group is directly transmitted to the MCU as the optimal parameter group; if M is greater than 1, the optimal parameter group selection unit calculates the percentage deviation o between the peak power Om and the expected peak power in the standard beam information (including peak power Om, average power Pm, and pulse width Qm) according to the standard beam information corresponding to the M first parameter groups; calculates the percentage deviation p between the average power Pm and the expected average power in the standard beam information; calculates the percentage deviation q between the pulse width Qm and the expected pulse width in the standard beam information; and sends the calculation results to the MCU, and the MCU selects the first parameter group corresponding to the standard beam information with the smallest (o+p+q) as the optimal parameter group. The optimal parameter group selection unit is electrically connected to the MCU; the MCU sends the optimal parameter group information to the power supply module 3 as a power parameter signal.

[0038] Specifically, the optimal parameter group selection unit is an important component of the FPGA in QCW mode, used to select the optimal parameter group. When there are M first parameter groups, if M is 1, the group is directly passed to the MCU as the best; if M is greater than 1, the deviation percentages o, p, and q from the desired parameters are calculated based on the standard beam information (including peak power Om, average power Pm, and pulse width Qm) corresponding to the M first parameter groups, and the results are transmitted to the MCU, which selects the first parameter group with the smallest (o+p+q) as the optimal parameter group and sends it to the power supply module 3 through the power parameter signal.

[0039] In this embodiment, under QCW mode, the optimal parameter set can be accurately selected for the system. By comprehensively considering the deviations of multiple parameter sets from the desired parameters, the laser can achieve optimal performance, ensuring that the laser output meets expectations and improving system performance and processing quality. This unit ensures the scientific and rational selection of parameters in QCW mode, enhances the stability and reliability of the system, and can better adapt to different application requirements.

[0040] In some implementations, the control module 422 includes a mode switching unit, which is communicatively connected to the power supply module 3; The mode switching unit is used to send a CW mode signal to the light source output module 1 and the power supply module 3 when the desired peak power is in the first peak power range, so that the light source output module 1 remains in CW mode. The mode switching unit is also used to send a QCW mode signal to the light source output module 1 and the power supply module 3 when the desired peak power is in the second peak power range, so that the light source output module 1 switches to QCW mode. The peak power in the first peak power range is less than the peak power in the second peak power range.

[0041] Specifically, in this embodiment, the mode switching unit is an important component of the controller 4. Its main function is to determine the operating mode of the laser based on the range of the desired peak power. It closely monitors the value of the desired peak power and compares it with a preset first peak power range and a preset second peak power range.

[0042] When the desired peak power is within the first peak power range, the mode switching unit sends a CW mode signal to the light source output module 1 and the power supply module 3. This operation means that the system will operate in CW mode, i.e., continuous wave mode. In this mode, the laser will output a laser beam in a relatively stable continuous wave form. After receiving the CW mode signal, the light source output module 1 will adjust its operating state to achieve continuous wave output; the power supply module 3 will provide the light source output module 1 with a power supply suitable for continuous wave mode according to the received CW mode signal, for example, by providing a stable current to maintain continuous laser output.

[0043] When the desired peak power is within the second peak power range (where the peak power is greater than that of the first peak power range), the mode switching unit sends a QCW mode signal to the light source output module 1 and the power supply module 3, causing the light source output module 1 to switch to QCW mode, i.e., quasi-continuous wave mode. In this case, the power supply module 3 will adjust its output power parameters according to the received QCW mode signal to meet the requirements of the quasi-continuous wave mode. This may involve adjusting parameters such as duty cycle, amplitude, and second current value, thereby enabling the laser to output a laser beam in the form of a quasi-continuous wave.

[0044] The communication connection between the mode switching unit and the power supply module 3 ensures that the mode switching signal can be accurately and timely transmitted to the power supply module 3 so that it can make corresponding adjustments to the power output. This communication connection can be implemented through a specific communication protocol or communication line, such as using digital signals to transmit information through a control bus, ensuring that the mode switching command can be correctly received and executed by the power supply module 3.

[0045] In this embodiment, the mode switching unit brings advantages to the laser system in many aspects, such as performance optimization, energy management and ease of use, through monitoring the desired peak power and automatic mode switching. It is an important component of the entire laser parameter intelligent control device, improving the system's intelligence, flexibility and applicability.

[0046] In some implementations, the controller 4 also includes a prompting module; The prompt module is used in QCW mode to display "Operation Normal" when the MCU determines that the expected pulse width is within the first pulse width range; The prompt module is also used in QCW mode to display a "data abnormality" warning signal when the MCU determines that the expected pulse width is in the second pulse width range; The pulse width value in the first pulse width interval is smaller than the pulse width value in the second pulse width interval.

[0047] Specifically, in this embodiment, the prompting module is an important component of the controller 4, mainly responsible for monitoring and prompting the desired pulse width in QCW (quasi-continuous wave) mode. It works closely with the MCU to display corresponding information based on the MCU's judgment of the desired pulse width.

[0048] In QCW mode, when the MCU determines that the expected pulse width is within the first pulse width range, the prompt module will display the message "Operation Normal". This indicates that the current expected pulse width is within the set normal range, and the system is expected to operate normally. This information can be displayed in various ways, such as through the device's display screen, indicator lights, or by sending the information to a remote monitoring system or user terminal, allowing users or operators to know that the system is currently within the normal expected pulse width range and to have a clear understanding of the system's operating status.

[0049] When the MCU determines that the expected pulse width is within the second pulse width range (where the pulse width value is greater than that of the first pulse width range), the prompt module will display a "Data Abnormality" warning signal. This warning signal is intended to notify the user or operator that the current expected pulse width exceeds the normal range, which may have a potential impact on the normal operation of the system. This warning signal can be presented in different forms, such as an alarm sound, flashing lights, or a prominent error message displayed on the screen, to attract the user's attention and allow for timely appropriate action.

[0050] In this embodiment, the prompt module provides users with an intuitive means of monitoring the system's operating status. Especially in the monitoring of the expected pulse width in QCW mode, users can quickly understand whether the current system is within the normal expected pulse width range through the information provided by the prompt module, without having to analyze the detailed parameters of the system or look at complex data, thus improving the user's ability to perceive the system's operating status.

[0051] For example, during laser processing, operators can promptly confirm whether the system is operating within the expected pulse width based on the prompts, avoiding processing quality degradation or equipment damage caused by abnormal pulse widths. When the expected pulse width is in the second pulse width range, the prompt module displays a "data abnormality" warning signal, serving as an early warning system. It can detect potential problems in advance, helping to prevent system failures or performance degradation caused by abnormal pulse widths.

[0052] Users or maintenance personnel can use this warning signal to promptly check and adjust system parameters, avoiding potential hazards and ensuring system stability and reliability. This is particularly important in applications with stringent pulse width requirements, such as high-precision laser material processing and laser medicine. Timely anomaly warnings can reduce product quality issues or medical accidents caused by pulse width abnormalities. Through real-time operational status monitoring and anomaly warnings, the alert module helps improve the reliability of the entire laser system. As the system's "guardian," it constantly monitors the status of key parameters (desired pulse width). Once an anomaly occurs, it can quickly issue a signal, allowing operators to intervene and resolve the problem at an early stage, preventing small problems from escalating into major failures, reducing losses and downtime caused by system malfunctions, and ensuring the stable operation of the laser system throughout its operation.

[0053] In summary, the prompting module plays a crucial role in monitoring the system's operational status, providing early warnings of anomalies, and enhancing system reliability by monitoring the desired pulse width and displaying corresponding information in QCW mode. It offers users a more user-friendly and reliable operation and maintenance experience, and improves the performance and safety of the laser system in various application scenarios.

[0054] In some implementations, the control module 422 further includes a first computing unit, a first status control unit, and a first warning unit; The first calculation unit is used to calculate the average power difference between the actual average power and the expected average power; The state control unit is used to control the light source output module 1 to maintain the current state when the average power difference is within the range of the desired average power. The warning unit is used to control the light source output module 1 to issue a warning signal when the average power difference exceeds the expected average power range.

[0055] Specifically, in this embodiment, the main function of the first calculation unit is to calculate the difference between the actual average power and the expected average power, providing a basis for subsequent decision-making; when the average power difference is within the expected average power range, the first state control unit ensures that the laser maintains its current state to ensure stable system operation and avoid unnecessary adjustments and fluctuations; when the average power difference exceeds the expected average power range, the first warning unit controls the laser to issue a warning signal, which can remind the user or operator through sound, light or display, indicating abnormal system operation.

[0056] In this embodiment, the first state control unit can maintain stable system operation, reduce unnecessary adjustments caused by small deviations, and ensure that the laser works continuously and efficiently; the first warning unit can promptly detect and notify the user of abnormal average power, enabling the user to take measures quickly to avoid problems such as system performance degradation and processing quality deterioration caused by abnormal power, thereby improving the reliability and maintainability of the system.

[0057] In some embodiments, the control module 422 further includes a first adjustment unit, which is electrically connected to the power supply module 3. When the average power difference exceeds the expected average power range and the actual peak power is less than the expected peak power, the adjustment unit sends an instruction to the power supply module 3 to adjust the first current value or the second current value according to the first step value. When the average power difference exceeds the expected average power range and the actual peak power is greater than the expected peak power, the adjustment unit sends an instruction to the power supply module 3 to adjust the first current value or the second current value according to the second step value. The first step has a positive value, and the second step has a negative value.

[0058] Specifically, in this embodiment, the first adjustment unit is part of the MCU and functions when the average power difference exceeds the expected average power range. It sends instructions to the power supply module 3 based on the relationship between the actual peak power and the expected peak power. If the actual peak power is less than the expected peak power, it sends an instruction to adjust the first or second current value by a positive first step value to increase the power; if the actual peak power is greater than the expected peak power, it sends an instruction to adjust the first or second current value by a negative second step value to decrease the power. It transmits information with the power supply module 3 via a signal connection.

[0059] In this embodiment, the first adjustment unit can precisely adjust the first current value or the second current value based on the comparison between the actual peak power and the expected peak power, thereby achieving effective control of the laser power and bringing the laser output power closer to the expected level to ensure system performance. This unit provides an automatic correction mechanism that does not require manual intervention. When a power deviation occurs, it can automatically adjust, improving the automation level of the system, ensuring stable laser output, and reducing the impact of power deviation on system performance.

[0060] In some embodiments, the control module 422 further includes a second calculation unit, a second state control unit, and a second warning unit. The second calculation unit includes: The single-pulse energy calculation unit is used to calculate the actual single-pulse energy of the light source output module 1 according to the single-pulse energy formula.

Peak power difference calculation unit, used to calculate the peak power difference between the actual peak power and the expected peak power; The second state control unit is used to control the light source output module 1 to maintain the current state when the actual peak power difference is within the expected peak power range; The second warning unit is used to control the light source output module 1 to issue a warning signal when the peak power difference exceeds the expected peak power range.

[0061] Specifically, in this embodiment, the single-pulse energy calculation unit calculates energy according to the formula... Calculate the actual single pulse energy This provides a basis for evaluating the energy characteristics of lasers; the actual peak power calculation unit is based on... Calculate the actual peak power This helps in understanding the power performance of the laser; the peak power difference calculation unit calculates the actual peak power. The difference between the power and the expected peak power provides a data basis for subsequent adjustments; the second state control unit maintains the current state when the difference is within the expected range to ensure stable operation; the second warning unit issues a "data abnormality" warning signal when the difference exceeds the range to remind the user.

[0062] In this embodiment, these units can accurately calculate and monitor key performance indicators of the laser, such as single-pulse energy and peak power, to help users understand the system status; they can ensure stable operation of the system under normal conditions and issue warnings when abnormalities occur, which helps users to discover and solve problems in a timely manner, thereby improving system reliability and performance.

[0063] In some embodiments, the control module 422 further includes a second adjustment unit, configured to adjust the amplitude according to a third step value when the peak power difference exceeds the expected peak power range and the actual peak power is less than the expected peak power; and to adjust the amplitude according to a fourth step value when the peak power difference exceeds the expected peak power range and the actual peak power is greater than the peak power; wherein the third step value is a positive number and the fourth step value is a negative number; The third adjustment unit is used to adjust the duty cycle according to the fifth step value when the actual pulse width is less than the expected pulse width; and to adjust the duty cycle according to the sixth step value when the actual pulse width is greater than the pulse width; wherein the fifth step value is negative and the sixth step value is positive.

[0064] Specifically, in this embodiment, when the actual peak power is less than the expected peak power, it indicates that the laser's output energy is insufficient and the power needs to be increased. The output power can be increased by adjusting the amplitude according to the third step value (positive number), as amplitude and output power are positively correlated. Conversely, when the actual peak power is greater than the expected peak power, the power needs to be reduced by adjusting the amplitude according to the fourth step value (negative number) to decrease the output power and bring it to the desired level. This allows for precise adjustment of the laser's peak power to meet the requirements of different application scenarios.

[0065] When the actual pulse width does not match the expected pulse width, the duty cycle needs to be adjusted. If the actual pulse width is less than the expected pulse width, the duty cycle is adjusted by the fifth step value (negative) to increase the pulse width; if the actual pulse width is greater than the expected pulse width, the duty cycle is adjusted by the sixth step value (positive) to shorten the pulse duration and reduce the pulse width. Adjusting the duty cycle allows for precise control of the pulse's timing characteristics, meeting the pulse width requirements of different applications.

[0066] In this embodiment, these two units can specifically adjust the amplitude and duty cycle to precisely adjust the system parameters, ensuring that the laser performance meets expectations and that the output laser power and pulse width meet the requirements. This helps to optimize the laser performance, maintain stable system operation, reduce performance fluctuations caused by parameter deviations, and improve the reliability and accuracy of system operation.

[0067] In some embodiments, the control module 422 further includes a fourth adjustment unit, used to adjust the amplitude and duty cycle according to a seventh step value when the peak power difference exceeds the expected peak power range and the actual peak power is less than the expected peak power; and to adjust the amplitude and duty cycle according to an eighth step value when the peak power difference is outside the expected peak power range and the actual peak power is greater than the peak power; wherein the seventh step value is a positive number and the eighth step value is a negative number.

[0068] Specifically, the fourth adjustment unit is part of the MCU and functions when the peak power difference exceeds the expected range. If the actual peak power is less than the expected peak power, the amplitude and duty cycle are adjusted simultaneously in positive seventh step increments to increase the output power; if the actual peak power is greater than the expected peak power, the amplitude and duty cycle are adjusted simultaneously in negative eighth step increments to decrease the output power. Through comprehensive adjustment of the amplitude and duty cycle, the system attempts to bring the actual peak power closer to the expected peak power.

[0069] In this embodiment, the unit can simultaneously adjust the amplitude and duty cycle, taking into account the combined effect of both on the peak power, making the adjustment more systematic and coordinated, and more effectively bringing the laser's output power closer to the desired level; it helps to improve system performance, ensuring that when the laser's peak power deviates, the performance can be restored or optimized through the adjustment of this unit, ensuring stable system operation, and reducing performance degradation and errors caused by power deviation.
