[0045] In the embodiments provided in the present application, a pulse laser used to realize different functions and generate corresponding performance parameters to be tested is connected to a control device, and the test items of various performances of the pulse laser are pre-set by the control device; at least two test devices are respectively connected to the control device, and the test device is used to analyze and test the performance parameters to be tested of the pulse laser, and the obtained test results are sent to the control device, so that the control device records the corresponding performance test results.

[0046] See also Figure 1 , Figure 1 : is a schematic diagram of a performance test system for a pulsed laser provided in an embodiment of the present application, the system comprising:

[0047] The pulse laser 01 is used to realize different functions to generate corresponding performance parameters to be measured.

[0048] The pulse fiber laser provided in the embodiment of the present application can have a variety of different functions. When testing, different performance parameters to be tested are generated according to the realization of different functions. The pulse laser 01 can have more choices in pulse waveform and operating frequency according to customer needs, and is widely used in new energy battery processing, material cleaning and paint removal, cutting, welding, marking and other fields of various metal materials and non-metal materials.

[0049] The performance test system also includes a control device 02 connected to the pulse laser 01. The control device 02 pre-sets the test items of various performances of the pulse laser 01 and records the corresponding performance test results. The control device 02 can be a PC or other control terminal with data processing capability and display function.

[0050] It also includes N test devices, where N is a positive integer not less than 2. One end of the test devices 1, ..., and N is connected to the control device 02. When the pulse laser is working, the test device receives the corresponding signal, and different test devices test and analyze different performance parameters of the pulse laser, and send the obtained test results to the control device 02, so that the control device 02 can automatically record different test parameters and performance parameters of the pulse laser 01.

[0051] In another embodiment provided in the present application, the pulse laser 01 can be connected to the control device 02 (such as PC end) through the first serial port line. The above-mentioned N test devices include at least two of an optical power meter, an oscilloscope, and a spectrometer. Among them, the optical power meter can be connected to the control device 02 through the second serial port line, the spectrometer can be connected to the control device 02 through the third serial port line, the oscilloscope can be connected to the control device 02 through a network cable, and the oscilloscope can also be connected to the control device 02 wirelessly. In this embodiment, the oscilloscope is set and the data is transmitted through the network cable, and the power meter and spectrometer are controlled by the serial port line to set parameters and transmit data; the calibration adopts a combination of dichotomy and adaptive step size, and a large step size is used at the beginning to quickly narrow the search interval of the current. When the pulse approaches the target, it switches to the adaptive step size for fine adjustment; the initial current adopts a regression model based on machine learning, and the data source is the corresponding current in each mode, and the initial current value is retrieved from the database to improve the calibration efficiency.

[0052] The performance testing system provided in the present application may also include a standard fixture, a rotatable and adjustable detector, a reflective plate, etc., and corresponding equipment may be installed according to test requirements.

[0053] In another embodiment provided by the present application, all devices in the performance testing system (including pulsed lasers, test equipment, control equipment, etc.) are controlled by a serial port line, and the test data is transmitted to a designated location network via a LAN line, making it convenient for relevant personnel to query and extract data for analysis and processing.

[0054] When testing, the initial value of the working current of the pulse laser 01 is obtained from the database through the host computer, and the adjustment method is pre-set in the control device 02 to perform the first pulse adjustment. Among them, the above-mentioned host computer can be a software for controlling the pulse laser and recording data written according to needs, which can be integrated in the control device 02 or in other terminals with data processing capabilities. The above-mentioned database stores data such as the working current, pulse waveform amplitude, pulse waveform half-height width, laser output optical power, etc. in each working mode of the pulse laser 01.

[0055] First, the pulse laser 01 is tested in the initial mode, and then the working mode is automatically changed through the control terminal 02. After the mode is changed through the database, the initial working current value of the pulse laser 01 in the current working mode is read and compared with the height of the first pulse displayed on the oscilloscope. The working current of the corresponding mode is adjusted by negative feedback until it meets the requirements to complete the calibration. The PID control algorithm can be used for calibration. This method is often used for automatic adjustment of nonlinear systems. By controlling the proportional (P), integral (I), and differential (D) terms of the control system, the current can be adjusted according to the error to ensure rapid convergence and no overshoot, thereby improving the precision of the adjustment and the safety of the test process.

[0056] After the calibration is completed, the equipment is manually replaced to test the output optical power, pulse waveform, spectrum and other performance parameters of the pulse fiber laser in each mode. After the test is completed, the control device 02 automatically reads and records the power, pulse waveform key data, and spectrum key data and stores the data. Repeat the above process by rotating the adjustment fixture to test the next amplifier stage.

[0057] In the embodiments provided in the present application, a pulse laser used to realize different functions and generate corresponding performance parameters to be tested is connected to a control device, and the test items of various performances of the pulse laser are pre-set by the control device; at least two test devices are respectively connected to the control device, and the test device is used to analyze and test the performance parameters to be tested of the pulse laser, and the obtained test results are sent to the control device, so that the control device records the corresponding performance test results. By setting various test modes and other information in the control device in advance, fully automated testing of various parameters of the pulse laser is achieved, and multiple devices can also be tested collaboratively to improve production efficiency. After the test, the test process parameters and test results are automatically recorded, which reduces the use of manual recording and paper jams, forms an electronic process card, facilitates data analysis and processing, and realizes green office, energy saving and environmental protection.

[0058] Another embodiment of the present application also provides a performance test method for a pulsed laser, which is applied to a control device in the performance test system provided in the above embodiment, such as Figure 2 The performance test method shown includes:

[0059] Step 201, obtaining the initial operating current of the pulse laser in the current test mode, and the first pulse height corresponding to the initial operating current.

[0060] Step 202, adjusting the operating current of the pulse laser to a specified range according to the first pulse height to complete the test calibration.

[0061] In another embodiment provided by the present application, the step of adjusting the operating current of the pulse laser to a specified range according to the height of the first pulse includes:

[0062] Determine whether the height of the first pulse is within a preset height range.

[0063] If the first pulse height is higher than the upper limit of the preset height range, the value of the initial working current is increased until the pulse height corresponding to the adjusted current is within the preset height range.

[0064] If the first pulse height is lower than the lower limit of the preset height range, the value of the initial working current is reduced until the pulse height corresponding to the adjusted current is within the preset height range.

[0065] In another embodiment provided in the present application, the method of adjusting the operating current of the pulse laser to a specified range according to the first pulse height also includes: if the first pulse height is within the preset height range, using the initial operating current as the operating current after test calibration.

[0066] Specifically, the height (current) of the first pulse is adjusted to be fixed, and each mode needs to adjust the working current according to the height of the first pulse. When the working current is low, the pulse sequence shows that the first pulse is high, and the working current needs to be increased; when the working current is high, the pulse sequence shows that the first pulse is low, and the working current needs to be reduced. Until the pulse height falls within the preset height range. The corresponding current values ​​and pulse widths in different modes can be found in the table below.

[0067]

[0068] When setting the above preset height range, it is possible to consider aspects such as the reasonable allocation of the laser amplifier gain and the long-term working stability and reliability of the laser. For example, the height of the first pulse of working modes 7 to 12 is consistent with the height (amplitude) of the subsequent flush pulse sequence (average value of the 5th to 1st pulse), the height of the first pulse of working modes 13 to 25 is 70% of the height of the subsequent flush pulse sequence, and the height of the first pulse of other modes is 50% of the height of the subsequent flush pulse sequence. The specific implementation process can be determined according to actual applications and is not limited here.

[0069] Step 203: Turn on the pulse laser within the specified range to instruct the test equipment to test various parameters of the pulse laser in the current mode.

[0070] The various parameters include at least one or more of output power, pulse waveform, and spectrum.

[0071] In another embodiment provided by the present application, the test of various parameters of the pulse laser in the current mode includes: after the test equipment is connected, fixing the output end of the pulse laser by a standard fixture; adjusting the amplification level of the pulse laser to test various parameters of the pulse laser at different amplification levels. After adjusting the amplification level of the pulse laser, the first amplification level couples the signal light into the photodetector by spatial coupling, and the amplification level after the first amplification level couples the signal light to the photodetector by reflection.

[0072] In another embodiment provided by the present application, the performance testing method further includes: reading and recording key data in the various parameters.

[0073] The embodiments provided in this application can realize fully automated testing and multi-device collaborative testing through the above method, thereby improving production efficiency.

[0074] In another embodiment provided by the present application, a fiber pulse laser is used as an example to describe in detail the process of automatic testing of multiple parameters:

[0075] Step 1: Connect the pulse laser, control equipment (such as PC) and various test equipment according to the test process requirements.

[0076] Step 2: The output power required for each amplifier stage is automatically calculated by inputting the seed source power and the target power of the whole machine through the control device, and the control device reads the database data to automatically set the initial current.

[0077] Step 3: The control device (such as a PC) controls the laser and the power meter to adjust the laser operating current by negative feedback until the target power of the current amplifier level is reached.

[0078] Step 4: After the current adjustment is completed, the final current and power will be automatically recorded in the test table.

[0079] Step 5: Replace the test equipment and fix the output end of the amplifier stage to be tested with a standard fixture. The first amplifier stage couples the signal light into the photodetector by spatial coupling, and the subsequent amplifier stage couples the signal light to the photodetector by reflection (see attached). Figure 3 The detector can be rotated to adjust its direction);

[0080] Step 6: The control device (such as PC) adjusts the first pulse of the laser. The height of the first pulse needs to be consistent with the height of the subsequent pulse sequence.

[0081] Step 7: After the adjustment is completed, the first pulse current will be automatically saved in the test table.

[0082] Step 8: Change the mode. Under the premise of keeping the height of the first pulse unchanged, the control device (such as PC) combines with the oscilloscope to adjust the working current of other modes through negative feedback. It is necessary to set the current for the power reduction frequency point and pulse pump frequency point of each mode respectively. The slope and intercept of the curve are calculated according to the internal algorithm based on the frequency and current linearity. The parameters are automatically calculated and recorded in the chip memory to ensure that each mode works at a frequency point below the pulse frequency point to start the pulse pump. The current from the pulse pump frequency point to the power reduction frequency point is linear according to the actual working frequency, and the working current is kept consistent at frequencies greater than the power reduction frequency point.

[0083] Step 9: Automatically record the current after each mode adjustment is completed into the test table.

[0084] Step 10: Replace the equipment and start testing the key data of the spectrum diagram, key data of the pulse waveform (amplitude, positive pulse width), and output optical power of all mode signal lights in the laser mode table after passing through the first amplification stage, and record the test results in the test table.

[0085] Step 11: Take a screenshot to save the calibration and test data. The method for each amplification stage is the same. Repeat steps 2 to 10 to complete the test of the working performance parameters of each mode of the pulsed laser.

[0086] In this embodiment, a standard test adjustable fixture is introduced to standardize the test process and improve the test safety; the test process parameters and test results are automatically recorded, which reduces the use of manual recording and abortion card paper, forms an electronic process card, facilitates data analysis and processing, and realizes green office, energy saving and environmental protection.

[0087] The following is a detailed description of the pulse laser test solution provided by the present application. Figure 4 As shown:

[0088] First, the target power, working current and other data of the pulse laser in each working mode are set in advance in the control device. At the beginning of the test, the initial value of the working current of the pulse laser in the current mode is obtained according to the pre-set information. The pulse laser starts working under the initial value of the working current. The test equipment receives various information sent by the pulse laser after working, and compares the actual output power of the pulse laser with the set target power (here, the pulse height can also be analyzed to adjust the current by negative feedback) to adjust the working current of the pulse laser. When adjusting the current, it is performed according to the preset amplitude and a limited number of steps are adjusted. The specific number of adjustment steps can be set as needed. If the actual output power of the pulse laser still does not reach the preset target power after the limited number of steps is adjusted, the test is judged to be unqualified and the equipment problem needs to be found. If the set target power is reached after the limited number of steps is adjusted, full mode calibration is performed. Continue to test the actual output power, pulse waveform, spectrum and other performance parameters of the pulse laser in different working modes, and the control device records the key performance parameters in the test data, such as amplitude, positive pulse width, key data of the spectrum diagram, etc., which are not listed one by one here.
