[0002] Ultrafast lasers represent a new area of ​​development in solid-state lasers. Ultrafast pulses, characterized by extremely short durations, extremely high peak powers, and extremely broad spectra, have found widespread application in numerous fields, including industry, military, environment, energy, and communications. Therefore, research on ultrafast lasers holds significant value and profound implications for scientific and social development, and has become a key focus of current scientific research.

[0003] Currently, solid-state lasers, including solid-state ultrafast lasers, are typically single-mode lasers, capable of processing solid workpieces in a single mode. If a solid-state laser is used in this single mode to process workpieces made of other materials, the laser's optical quality will be poor, and its output power and energy will not meet processing requirements. In severe cases, it can also cause hardware wear on the solid-state laser, shortening its lifespan. To address this issue, multi-mode solid-state lasers have emerged.

[0047] The above drawings illustrate specific embodiments of the present application, which will be described in more detail below. These drawings and the textual description are not intended to limit the scope of the present application in any way, but rather to illustrate the concepts of the present application to those skilled in the art by reference to specific embodiments. DETAILED DESCRIPTION

[0048] Exemplary embodiments are described in detail herein, with examples illustrated in the accompanying drawings. When the following description refers to the drawings, identical numerals in different drawings represent identical or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all embodiments consistent with this application.

[0049] Existing solid-state lasers are usually single-mode, using a fixed fundamental frequency. At high repetition rates, the output pulse energy decreases as the repetition rate increases. In particular, for ultraviolet or green ultrafast lasers, the power of different pulse trains generated at different repetition rates varies significantly due to temperature. Therefore, single-mode lasers cannot maintain stable pulse energy within a certain frequency range. In addition, they have the disadvantages of single application, fixed process, fixed processing materials, and limited options. Even if multi-mode solid-state lasers exist in the existing technology, their control methods still have the technical problem of being unable to effectively expand the application range of solid-state lasers.

[0050] In order to solve the above technical problems, the overall inventive concept of the present application is to provide a multi-mode control method applied to the technical field of laser mode control and used to improve the applicability of solid-state lasers.

[0051] The following specific embodiments describe in detail the technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0052] Example 1:

[0053] Figure 1 This is a flow chart of a multi-mode control method for a solid-state laser provided in an embodiment of the present application. Figure 1 As shown, the method of this embodiment includes the following steps S101 to S103, wherein:

[0054] S101: Obtaining information on the requirements of the workpiece for the solid-state laser.

[0055] It should be understood that solid-state lasers include solid-state ultrafast lasers. In embodiments of the present application, attribute information of a workpiece to be processed, including material information and thickness information, can be first acquired. The attribute information can then be used to automatically determine the solid-state laser requirements for the workpiece. The requirements can include at least one of the following: fundamental frequency, number of pulses, and pulse amplitude.

[0056] S102: Determine a target mode of the solid-state laser corresponding to the required information, and search for target mode parameters of the solid-state laser in a preset database.

[0057] In the embodiments of the present application, the target mode parameters of the solid-state laser are parameter information pre-configured for the solid-state laser in the target mode. Such parameter information includes at least one of the following: pump source parameters, temperature parameters, repetition rate, power ratio parameters, and power monitoring coefficient. The repetition rate is short for the reference repetition rate.

[0058] For example, for the same type of solid-state laser, if the required information is group A, the target mode corresponding to group A is mode A; if the required information is group B, the target mode corresponding to group B is mode B; and if the required information is group C, the target mode corresponding to group C is mode C. The parameter information group in mode A, the parameter information group in mode B, and the parameter information group in mode C may differ in the configuration of any one or more of the following parameters: pump source parameters, temperature parameters, repetition rate, and power ratio parameters.

[0059] S103: When it is determined that the solid laser is in the standby mode, a control instruction corresponding to the target mode parameter is sent to the solid laser, so that the solid laser switches from the standby mode to the target mode based on the control instruction, and processes the workpiece according to the parameter information in the target mode.

[0060] It should be understood that switching modes in standby mode can improve the safety of solid-state lasers. For example, if the target mode is B mode and the current mode is A mode, switching directly from A mode to B mode can easily damage the hardware structure of the solid-state laser. Therefore, in this case, the embodiment of the present application first switches the solid-state laser from A mode to standby mode, and then switches from standby mode to B mode.

[0061] By executing the above steps S101 to S103, the multi-mode control method of the solid-state laser provided in the embodiment of the present application has the following specific advantages: on the one hand, this embodiment expands the application range of the solid-state laser, and the same equipment can achieve effective cutting of different thicknesses and different materials; on the other hand, based on the selection of different fundamental frequencies, it provides more options for process parameter optimization and widens the adjustable range of the processing speed of the solid-state laser.

[0062] The multi-mode control method of the solid-state laser provided in the embodiment of the present application can be implemented on the controller of the solid-state laser. The controller can be provided with laser control software, which can intelligently realize effective mode switching of the solid-state laser, and then quickly switch to the corresponding target mode according to the processing requirements of different workpieces to be processed, and perform processing according to the target mode parameters, thereby effectively expanding the application range of the solid-state laser.

[0063] In a possible implementation, after searching for the target mode parameters of the solid-state laser, the multi-mode control method of the solid-state laser further includes the following steps S104 to S105, wherein:

[0064] S104: Determine whether the current mode of the solid-state laser is the standby mode.

[0065] S105: When it is determined that the current mode of the solid-state laser is not the standby mode, a standby instruction is sent to the solid-state laser to switch the solid-state laser from the current mode to the standby mode.

[0066] By executing S104 to S105, the embodiment of the present application can ensure that the solid-state laser performs mode switching in the standby mode, thereby improving the safety of the solid-state laser and extending its service life.

[0067] Based on the above embodiments, the technical solution of the present application is described in more detail below in combination with several specific embodiments.

[0068] Example 2:

[0069] Figure 2 Provided in the embodiments of this application Figure 1 Schematic diagram of the process of S102. Figure 2 is Figure 1Based on the above, the expanded description of step S102 is as follows: in step S102, searching the preset database for the target mode parameters of the solid-state laser includes the following steps S1021 to S1022, wherein:

[0070] S1021: Identify identification information of the solid-state laser, and search for a mode file of the solid-state laser from a preset database according to the identification information of the solid-state laser.

[0071] In the embodiment of the present application, the identification information of the solid-state laser can be referred to as an identity document (ID). Different types of solid-state lasers may have their identification information encoded in different ways. For example, there are three solid-state lasers, one of which is a first type of solid-state laser and the other two are a second type of solid-state laser. The identification information of the first type of solid-state laser can be encoded in binary code 1001, and the identification information of the second type of solid-state laser can be encoded in geographic location code: (1, 2), (2, 3), which is used to indicate its specific location in the production workshop.

[0072] The embodiment of the present application can set up only one preset database for different types of solid-state lasers, or can set up corresponding preset databases for different types of solid-state lasers. The advantage of setting up separately is that it speeds up the search speed.

[0073] S1022: According to the target mode of the solid-state laser, search for target mode parameters of the solid-state laser from the mode file of the solid-state laser.

[0074] For example, if the target mode of the solid laser 1001 is the B mode, the target mode parameters of the solid laser 1001 (including pump source parameters, temperature parameters, repetition rate, power ratio parameters, etc. in the B mode) are searched from the mode file of the solid laser 1001.

[0075] The embodiments of the present application can establish an association between the target mode and the target mode parameters through a preset database, thereby improving search efficiency and facilitating intelligent mode control of the solid-state laser.

[0076] In one possible implementation, Figure 3 As shown, building a preset database includes the following steps S301 to S305, wherein:

[0077] S301: configuring mode parameters of a solid-state laser, and after configuring the mode parameters, receiving quality evaluation information of the solid-state laser corresponding to the mode parameters obtained by a detection device of the solid-state laser.

[0078] In the embodiments of the present application, the solid-state laser detection device is also referred to as a laser optical quality detection device. Quality evaluation information includes: optical quality information, optical energy information, and power. Optical quality information includes, but is not limited to, laser spot quality and spot roundness. Optical energy information is also referred to as pulse energy, and power is reflected in pulse stability.

[0079] During the configuration of the mode parameters of a solid-state laser, the values ​​of each mode parameter can be adjusted arbitrarily based on the required information, so that mode parameters that meet the preset quality evaluation requirements can be subsequently screened. Furthermore, the more refined the configuration process, the more accurate the mode parameters in subsequent multi-modes. In the embodiments of the present application, the multi-mode solid-state laser can achieve stable pulse energy at multiple frequencies.

[0080] In related technologies, the manufacturing process of single-mode lasers is limited, such as in terms of power, frequency, delay, and other process configurations. However, this application proposes a multi-mode control method that can configure different repetition rates in different modes, select appropriate temperature, power monitoring coefficient, and other related mode parameters, so that the solid-state laser can output optimal pulse energy while maintaining the optical quality standards in different modes.

[0081] S302: According to the identification information of the solid-state laser, it is determined whether there is a table corresponding to the solid-state laser in the preset library table.

[0082] It should be understood that this table is an ID table, and one solid-state laser corresponds to one ID table.

[0083] S303: When it is determined that the table corresponding to the solid-state laser does not exist in the preset library table, a new table corresponding to the solid-state laser is created, and the mode parameters and the quality evaluation information are stored in the table corresponding to the solid-state laser.

[0084] In an embodiment of the present application, if a table corresponding to the solid-state laser exists in the preset library table, the step of creating a new one is omitted, and the mode parameters and quality evaluation information are directly stored in the table corresponding to the solid-state laser, and the table corresponding to the solid-state laser can be updated.

[0085] S304: Exporting the table corresponding to the solid-state laser as an intermediate file, and screening out mode parameters that meet preset quality evaluation requirements from the intermediate file.

[0086] It should be understood that the preset quality evaluation requirements are that the M square factor is less than 1.4 (ie, the above-mentioned requirements for the light spot quality), the light spot circularity is greater than 90%, and the pulse stability is less than 3%.

[0087] In an embodiment of the present application, when there are multiple groups of mode parameters in a mode that all meet the preset quality evaluation requirements, the embodiment of the present application can set a weight for each evaluation in the preset quality evaluation requirements, thereby achieving normalization processing of the multiple groups of mode parameters, that is, scoring the multiple groups of mode parameters. After scoring, one way is to retain the group of mode parameters with the highest score as the optimal mode parameters, and the second way is to retain the mode parameters with the top scores as the optimal mode parameters. When there is only one group of mode parameters in a mode, the laser switching of the solid-state laser can be achieved according to the group of mode parameters when the mode is switched subsequently; when there are multiple groups of mode parameters in a mode, the laser switching can be achieved according to the scoring sorting results when the mode is switched subsequently. When the solid-state laser fails to meet the preset quality evaluation requirements during the processing of the workpiece, other groups of mode parameters are selected in time according to the preset rules for switching. The preset rules can be the scoring arrangement order or other rules, and the embodiment of the present application does not make specific restrictions on this.

[0088] S305: creating a mode file of the solid-state laser in a preset format according to the identification information of the solid-state laser, and writing the mode file of the solid-state laser into a preset database; wherein the mode file of the solid-state laser is used to store mode parameters that meet preset quality evaluation requirements.

[0089] In the embodiment of the present application, the preset format may refer to an ASCII-based Braille Ready Format, referred to as BRF format. After the mode file of the solid-state laser is written into the preset database, it is convenient to export the file when the solid-state laser is subsequently controlled.

[0090] The light beam output by the solid-state laser passes through the laser optical quality detection device to obtain key values ​​such as the spot quality, spot roundness, pulse energy, stability and power of the solid-state laser. By changing different fundamental frequencies, number of pulses and amplitudes, the optimal current mode parameters are configured and saved. Multiple sets of mode parameters are stored in the same way, exported and stored as read-only mode files. In addition to multiple sets of mode parameters, the mode file can also contain the mode matching identifier and laser matching ID of the current laser. When switching the mode of the solid-state laser, the mode file is imported, the laser and mode file are verified, the mode is switched with one click, and the current mode parameters of the solid-state laser are configured.

[0091] Existing technologies are unable to switch modes and are unable to achieve optimal optical quality (e.g., M factor less than 1.4, spot circularity greater than 90%), pulse energy, and power (e.g., pulse stability less than 3%) for different pulse numbers and pulse amplitudes at different baseline repetition rates and temperatures. Compared to existing technologies, the mode file in the embodiments of this application stores the corresponding mode parameters of the solid-state laser at different baseline repetition rates and temperatures. Because these mode parameters are pre-screened, they can ensure optimal optical quality and optimal power.

[0092] In one possible implementation, after step S1021: searching a mode file of the solid-state laser from a preset database according to identification information of the solid-state laser, the multi-mode control method of the solid-state laser further includes:

[0093] S1023: Exporting the mode file of the solid-state laser from the preset database for re-storage, and displaying all modes of the solid-state laser and parameter information of the solid-state laser in all modes.

[0094] In the embodiment of the present application, the modes of the solid-state laser and the parameter information of the solid-state laser in the mode are editable, and the edited information can be displayed on the controller interface according to the display requirements. In addition, the embodiment of the present application also supports the user to enter the identification information of a solid-state laser in the query window, and then display all modes of the solid-state laser at the current moment and the parameter information of the solid-state laser in all modes.

[0095] The embodiment of the present application has the advantage of visualization. Since the mode of the solid-state laser is editable, the user can obtain the latest status of the solid-state laser in a timely and synchronous manner through display.

[0096] Example 3:

[0097] Figure 4 This is a flow chart of another multi-mode control method for a solid-state laser provided in an embodiment of the present application. Figure 4 As shown, the method of this embodiment includes:

[0098] S401: Obtaining the requirements of the workpiece for the solid-state laser.

[0099] It should be understood that the description of S401 can refer to the description of S101 and will not be repeated here.

[0100] S402: Determine whether the solid-state laser is a single-mode device.

[0101] S403: When the solid-state laser is a single-mode device and the solid-state laser meets the required information in the single mode, a power-on instruction is sent to the solid-state laser, so that the solid-state laser processes the workpiece in the single mode.

[0102] During mode control, a single controller can simultaneously control many solid-state lasers, including both multi-mode and single-mode devices. To achieve intelligent process control, the controller in this embodiment automatically determines whether the solid-state laser is multi-mode or single-mode, and then determines the subsequent process. The control software can display the results for the single-mode device on the controller's interface, and then the user can trigger it with a single button, causing the controller to send a power-on command to the single-mode device.

[0103] The above process only requires one-click operation by the user to realize multi-mode control of the solid-state laser, which is simple to operate and improves convenience and safety of operation.

[0104] The multi-mode control method for a solid-state laser in this embodiment mainly involves five parts: mode parameter configuration, mode parameter storage and export, mode file and laser matching verification, mode file call, mode switching, and system configuration. Mode parameter configuration is described in step S301 above, mode parameter storage and export are described in steps S302 to S304 above, mode file and laser matching verification is described in step S305, mode file call is described in steps S1021 to S1022 above, and mode switching and system configuration is described in step S103 above.

[0105] In general, this method first obtains the optimal configuration parameters of the solid-state laser under different modes, such as the reference repetition rate, pump source parameters, power ratio parameters, and temperature, and stores the configuration parameters to generate a mode file; secondly, when the solid-state laser is running, when the mode file is called, the mode file is matched with the laser ID. Only when they are completely matched can the mode parameters of the solid-state laser under different modes stored in the mode file be called, thereby realizing mode switching.

[0106] In summary, the multi-mode control method of the solid-state laser provided in the embodiments of the present application has the following advantages:

[0107] (1) By selecting different fundamental frequencies and pulse numbers, the pump source parameters, temperature parameters, repetition rate and other parameters of the solid-state laser can be optimized in one click, so that the solid-state laser has the best optical quality, power and pulse energy in different modes, meeting the multi-matching of the processing technology and adapting to different processing requirements.

[0108] (2) The acquisition of the mode file is based on monitoring the optical parameters of the laser output beam, such as the spot quality and roundness, as well as the monitored output power and pulse energy as quality evaluation information, and real-time tuning of the mode parameters of the solid-state laser. The main parameters include pump source parameters, temperature parameters, solid-state laser matching ID and repetition rate, pulse number and amplitude, etc.

[0109] (3) The import of the mode file is a one-click import through the laser control software. The laser control software can match the mode file corresponding to the current solid-state laser, and the mode file supports modification and reset without affecting the performance of the solid-state laser.

[0110] (4) This embodiment can achieve that the optical parameters of the solid-state laser, such as the spot quality and spot roundness, meet the standards under different fundamental frequencies, and the pulse energy and power output by the solid-state laser are optimized.

[0111] Example 4:

[0112] Figure 5 This is a schematic diagram of the structure of a multi-mode control device for a solid-state laser provided in an embodiment of the present application. The device of this embodiment can be in the form of software and / or hardware. Figure 5 As shown, the multi-mode control device for a solid-state laser provided in this embodiment includes: an acquisition module 51, a determination and search module 52, and a sending module 53.

[0113] The acquisition module 51 is used to obtain the requirements of the workpiece to be processed for the solid-state laser.

[0114] The determination search module 52 is used to determine the target mode of the solid-state laser corresponding to the required information and search for the target mode parameters of the solid-state laser in a preset database; wherein the target mode parameters of the solid-state laser are parameter information pre-configured for the solid-state laser in the target mode.

[0115] The sending module 53 is used to send a control instruction corresponding to the target mode parameter to the solid laser when determining that the solid laser is in the standby mode, so that the solid laser switches from the standby mode to the target mode based on the control instruction, and processes the workpiece according to the parameter information in the target mode.

[0116] In one possible implementation, the search module 52 is further configured to:

[0117] Identify identification information of the solid-state laser, and search for a mode file of the solid-state laser from a preset database according to the identification information of the solid-state laser.

[0118] According to the target mode of the solid-state laser, the target mode parameters of the solid-state laser are found from the mode file of the solid-state laser.

[0119] In one possible implementation, the multi-mode control device for a solid-state laser is further used to:
