Description

Technical Field

[0001] This invention relates to the field of fiber optics and laser technology, and in particular to an intelligent control system for fiber lasers based on the Electron architecture. Background Technology

[0002] With the rapid development of laser technology, fiber lasers, due to their advantages such as compact structure, high beam quality, high conversion efficiency, and good stability, have been widely used in various fields such as materials processing, medical equipment, communication transmission, and scientific research. The performance of fiber lasers is highly dependent on the accuracy and stability of their control systems, especially in areas such as laser output power, wavelength adjustment, frequency doubling control, and temperature management. Most existing fiber laser control systems adopt embedded microcontrollers or PLCs, resulting in complex interfaces, poor functional scalability, and difficulty in meeting the needs of modern intelligent manufacturing and remote control. Furthermore, software systems typically lack cross-platform capabilities, making maintenance and updates inconvenient and hindering subsequent upgrades and integration. Electron, a cross-platform desktop application development framework based on web technology, enables deep integration between the front-end interface and back-end hardware control. Developing fiber laser control systems using the Electron architecture can significantly improve system visualization, user interaction, and functional scalability, driving the development of lasers towards intelligence, modularity, and remote control. Summary of the Invention

This system aims to solve problems such as limited functionality, unfriendly interfaces, and poor scalability in existing fiber laser control systems. It achieves unified intelligent control of modules such as seed light sources, power amplifiers, and frequency multipliers, and possesses a user-friendly visual interface and system monitoring capabilities.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] The hardware control module includes a seed light source control unit, a power amplifier control unit, a frequency multiplier control unit, and an output laser monitoring unit; the power amplifier control unit, the frequency multiplier control unit, and the output laser monitoring unit are respectively used to amplify, multiply, and detect the seed laser generated by the seed light source control unit.

[0007] The software management platform is developed using the Electron architecture and integrates a seed light control interface, an amplifier control interface, a frequency multiplier adjustment interface, and a protection system.

Detailed Implementation

[0016] To make the objectives and technical solutions of this application clearer, the present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only for explaining the present invention, but should not be used to limit the scope of protection of the present invention.

[0017] like Figure 1 As shown, the present invention provides an intelligent control system for a fiber laser based on Electron architecture, including a hardware control module 5 and a software management platform 10; the hardware control module 5 includes a seed light source control unit 1, a power amplifier control unit 2, a frequency multiplier control unit 3, and an output laser monitoring unit 4; the software management platform 10 is developed using Electron architecture and integrates a seed light control interface 6, an amplifier control interface 7, a frequency multiplier adjustment interface 8, and a protection system 9.

[0018] In one embodiment, the hardware control module 5 and the software management platform 10 communicate via a serial port protocol.

[0019] In one embodiment, the seed light source control unit 1 includes a current drive module, a temperature control module, a laser diode, and an optical fiber path structure for generating a seed laser. Specifically, the current drive module provides a stable injection current to the laser diode to generate a seed module pump laser; the temperature control module uses a thermoelectric cooler (TEC) and a temperature sensor to form a closed-loop control, maintaining the laser diode's operating temperature stably to ensure the long-term stability of the output wavelength and power of the seed module pump laser. The optical fiber path structure includes a Bragg phase-shift grating, a wavelength division multiplexer, etc., to achieve single-frequency laser oscillation and ultimately output a stable single-mode seed laser. Users can set and adjust the output seed laser power and wavelength, and monitor the current and temperature status of the current drive module and the temperature control module through the seed light control interface 6 integrated in the software management platform 10.

[0020] In one embodiment, the power amplifier control unit 2 includes a pump driver and an amplifier optical path structure for power amplification of the seed laser output from the seed light source control unit. Specifically, the pump driver drives a multi-stage pump laser diode through a high-precision current source, and the amplifier optical path structure uses ytterbium-doped / erbium-doped fiber as the gain medium to enhance the power of the seed laser through cascaded amplification. Simultaneously, the optical path structure integrates an isolator and a mode matcher to suppress back radiation and optimize beam quality. Users can set the target amplification power in real time and monitor the pump drive current, amplifier internal temperature, and output power stability through the amplifier control interface 7 integrated in the software management platform 10, ensuring the efficiency and safety of the amplification process.

[0021] In one embodiment, the frequency multiplier control unit includes a temperature controller and a frequency doubling optical path structure for wavelength conversion (e.g., 1540nm → 770nm) of the amplified fundamental frequency light output from the power amplifier control unit. Specifically, the temperature controller precisely adjusts the operating temperature of the nonlinear crystal (e.g., MgO:PPLN) via a TEC to meet phase matching conditions; the frequency doubling optical path structure includes a focusing lens group and a resonant cavity mirror to improve conversion efficiency. Users can set the target temperature of the crystal and monitor the sampling temperature of the frequency doubling module through the frequency multiplier adjustment interface 8 integrated in the software management platform 10, thereby optimizing the generation of the second harmonic.

[0022] In one embodiment, the output laser monitoring unit 4 performs beam splitting monitoring on the output laser of the frequency doubling control unit 3 and transmits the monitoring data to the protection system 9.

[0023] In one embodiment, the software management platform 10 uses the Electron framework to build the main architecture of the application, implements graphical interface rendering based on the Chromium kernel, and integrates the underlying system interfaces through Node.js. The front-end interface of the software management platform 10 is developed using the Vue.js framework to achieve dynamic visualization of control parameters. Figure 2 As shown, Electron serves as the backend for the desktop application, communicating with the frontend Vue.js framework via ipcRenderer and ipcMain. The system possesses native cross-platform capabilities, maintaining consistent hardware control functionality and user experience across Windows, Linux, and macOS operating systems.

[0024] In one embodiment, the software management platform 10 centrally manages the seed light control interface 6, amplifier control interface 7, frequency multiplier adjustment interface 8, and protection system 9. Users set parameters through each interface, and the software management platform 10 distributes instructions to the corresponding units of the hardware control module 5, collecting feedback data in real time for monitoring. When abnormal parameters such as laser power, current, or temperature are detected, the system can immediately perform an emergency shutdown operation, such as shutting down the seed light source control unit 1, to ensure system safety.

[0025] In one embodiment, the startup process of the software management platform 10 is as follows: Figure 3 As shown, the process begins with page initialization, followed by user configuration of serial ports for each control unit. Then, the seed light control interface 6 is set to start seed light output, the amplifier control interface 7 is set to start amplifier output, the frequency multiplier adjustment interface 8 is set to start frequency multiplier output, and finally, the protection system 9 is started to monitor the system's operating status.

[0026] In one embodiment, addressing the unique challenge of synchronizing real-time interface updates with background data processing in laser control systems, this invention innovatively proposes a distributed serial port data processing architecture based on Node.js worker_threads. This solution specifically addresses the performance bottleneck in multi-channel concurrent serial port communication scenarios. By assigning the serial communication tasks of each hardware control unit (including the seed light source control unit 1, power amplifier control unit 2, frequency multiplier control unit 3, and output laser monitoring unit 4) to independent worker threads, the main process of the software management platform 10 is only responsible for task distribution and result aggregation. Efficient communication with worker_threads via MessageChannel significantly reduces the load on the main process, ensuring low-latency issuance of control commands and high-concurrency reception of monitoring data, thereby improving the performance of the Electron architecture.

[0027] In one embodiment, the present invention incorporates a data aggregation and throttling module based on the Electron framework within the main process of the software management platform 10. This module preprocesses the raw high-frequency data from various hardware units, performs mean filtering and change threshold judgment within a set time window, and only sends the aggregated key data to the ipcRenderer via ipcMain when the data change exceeds a preset threshold or reaches a specific time interval. This ensures that users can observe key state changes while significantly reducing the data update pressure on the rendering process, thus improving the smoothness of the Vue application UI in complex interfaces.

[0028] In one embodiment, to ensure the consistency of front-end and back-end data in the software management platform 10, this invention designs a communication protocol based on serial numbers and acknowledgment within the Electron framework. Each control command from the front-end is accompanied by a unique serial number. Only after the main process sends the command to the hardware via the serial port and receives confirmation from the hardware, does it send the execution result with the same serial number back to the front-end. This mechanism ensures closed-loop operation and strong consistency of state, avoiding mismatches between the front-end and back-end states due to communication delays or loss.
