Detailed Implementation

[0023] To make the objectives, advantages, and features of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of this utility model and are not intended to limit the scope of protection of this utility model.

[0024] Combination Figures 1 to 4 As shown, this embodiment provides a fast-response laser control system, including a chassis 20, a laser control unit, a power supply 22, a rocker switch, and a heat dissipation unit.

[0025] The chassis 20 is a rectangular shell, and the chassis 20 is equipped with a BNC signal trigger interface 11 and a waterproof fiber optic connector 12.

[0026] The laser control unit includes a voltage generation module, an analog signal transmission control board 25 and a light source module connected in sequence, as well as a trigger controller 26.

[0027] A voltage generation module is installed on the top of the chassis 20 and is used to output corresponding analog voltage signals to the analog signal transmission control board 25. The voltage generation module includes a debug mode voltage generator 3 and a working mode voltage generator 7, both installed on the top of the chassis 20 and connected to the power supply 22. These two generators are connected to the analog signal transmission control board 25 respectively and are used to output corresponding analog voltage signals to the analog signal transmission control board 25 in different working modes. The analog signal transmission control board 25 is equipped with a debug mode push-button switch 2 and a working mode push-button switch 6, both installed on the top of the chassis 20 and connected to the power supply 22. Pressing these switches allows the analog signal transmission control board 25 to be switched between working mode and debug mode.

[0028] The analog signal transmission control board 25, the light source module, and the trigger controller 26 are respectively installed inside the chassis 20. The analog signal transmission control board 25 converts the analog voltage signal into a corresponding voltage signal and transmits it to the light source module to control the laser output power. The light source module includes multiple light sources 19 and a combiner 21 installed inside the chassis 20. The input of each light source 19 is connected to the power supply 22 and the analog signal transmission control board 25, respectively, and its output is connected to the input of the combiner 21 via optical fiber. The output of the combiner 22 is connected to the fiber optic waterproof connector 12 via optical fiber. The fiber optic waterproof connector 12 is used to fix the output optical fiber (armored fiber). After fiber splicing, the connector is a QBH interface, which can withstand higher power. The fiber head is equipped with a dedicated dust cap. Before testing, the fiber dust cap is opened, and the output light is adjusted during testing. After testing, the dust cap is closed to prevent dust from entering. In some embodiments, the interface can also be adapted with different connectors as needed.

[0029] In this embodiment, the light source 19 is a semiconductor laser, which includes a laser diode, an optical fiber coupler, and a heat pipe radiator. The laser diode is connected to the power supply 22. By applying current to the laser diode, electrons and holes in the semiconductor material recombine, generating a laser beam. The input end of the optical fiber coupler is located at the output end of the laser diode, and the output end is connected to a beam combiner 21 via an optical fiber. This coupler is used to precisely couple the laser beam into the optical fiber and output it to the beam combiner 21, thereby achieving beam guidance and transmission. The laser energy propagates in the optical fiber, and thanks to its low-loss and high-bandwidth characteristics, it enables long-distance, high-speed data transmission or processing tasks. The heat pipe radiator is installed below the laser diode, and thermal grease needs to be applied during installation. The thermal grease should be applied as evenly as possible, avoiding uneven thickness. The heat pipe cooling technology provides efficient heat conduction. Fans are located on both sides of the heat pipe radiator for overall heat dissipation of the chassis 20.

[0030] The light emission method of light source 19 is as follows: power supply 22 supplies power to each light source 19, and the corresponding laser diodes are connected in series and soldered at the tail of the laser diodes. After all the soldering is completed, the corresponding voltage and current are input to emit light. The generated laser beam is precisely coupled into the optical fiber after fine adjustment by the fiber coupler and is stably transmitted along the path of the optical fiber. Then, it is combined and fused by the beam combiner 21, and a single optical fiber is output for high-power output through the waterproof fiber connector 12. The output optical fiber is fixed to the chassis 20 through the waterproof fiber connector 12. The output optical fiber finally emits a single green circular light spot. The actual output power of the laser beam can be controlled by rotating the adjustment knobs of the adjustment mode voltage generator 3 and the working mode voltage generator 7.

[0031] The light source module has a built-in temperature sensor that can monitor the light source temperature in real time, automatically adjust heat dissipation, prevent overheating, and improve the lifespan of the light source.

[0032] The input terminal of the trigger controller 26 is connected to an external trigger signal source through the BNC signal trigger interface 11, and the output terminal is connected to the analog transmission control board 25. The trigger signal is output to the analog transmission control board 25, and then the analog transmission control board 25 drives the light source module to emit a laser beam of corresponding power, which is output through the fiber optic waterproof connector 12.

[0033] The BNC signal trigger interface 11 is a BNC connector that enables BNC signal triggering. It comes with a BNC connecting cable, a BNC extension cable, a BNC dust cap, and a BNC adapter. The BNC signal trigger interface 11 is connected in series with the EXT interface of the trigger controller 26. The trigger controller 26 includes EXT, INT, RST, OUT, 12V, AI, and AO interfaces. The EXT interface is used for external signal triggering of the laser, outputting a high-level pulse or DC signal to trigger the laser (i.e., OUT outputs a high level). The INT interface is for internal triggering; it can be connected to a normally open button, pressing it once triggers the laser output. The RST interface is used to turn off the laser output; it can be connected to a normally open button, pressing it once turns off the laser output. The OUT interface is the laser trigger output signal, connected to the laser driver board; a high level outputs laser light, a low level turns off the laser. The 12V interface is the power input socket, requiring a 12V power supply 22. The AI ​​interface is for 0-5V analog signal input, and the AO interface is for 0-5V analog signal output.

[0034] A rocker switch 5 is mounted on the chassis 20 and connected to the power supply 22, which provides 220V AC power. The rocker switch 5 is used to control the on / off state of the power supply 22. The power supply 22 is installed inside the chassis 20 and is connected to the voltage generation module, analog signal transmission control board 25, light source module, and trigger controller 26, and is also connected to an external power supply.

[0035] The heat dissipation unit includes a fan speed controller mounted on the top of the chassis 20, a fan and fan driver board mounted inside the chassis 20, and ventilation holes 17 located on the side wall of the chassis 20 near the fan. The fan speed controller includes a debug mode fan speed controller 4 and a working mode fan speed controller 8, both connected to the power supply 22. The fan driver board includes a debug mode driver board 23 and a working mode driver board 24, both connected to the debug mode fan speed controller 4 and the working mode fan speed controller 8, respectively. These boards feature automatic fan speed adjustment to ensure system heat dissipation and extend equipment lifespan. There are two sets of fans; one set is connected to the debug mode driver board 23, and the other set is connected to the working mode driver board 24. The debug mode driver board 23 and the working mode driver board 24 drive their respective fans, monitoring temperature changes in real time and automatically adjusting the fan speed through the debug mode fan speed controller 4 and the working mode fan speed controller 8 to effectively prevent overheating and ensure stable laser operation.

[0036] This embodiment also includes a handheld switch to enable multiple triggering methods. The chassis 20 is equipped with a handheld switch retainer 9 and a manual trigger interface 10, the latter being an aviation connector. The handheld switch retainer 9 is used to hold the handheld switch; the handheld switch is connected to the analog signal transmission control board 25 via a BNC adapter cable passing through the manual trigger interface 10. When the handheld switch is pressed, it provides a circuit and outputs a laser beam; when released, it disconnects the circuit and no light is emitted.

[0037] Preferably, this embodiment also includes a delay trigger module 15 disposed on the chassis 20. Its input terminal is used to connect to an external trigger signal source, and its output terminal is connected to the AI ​​and AO interfaces of the trigger controller 26. It is used to receive delayed trigger signals and output them to the trigger controller 26. The delay trigger module 15 precisely controls the laser emission time through preset time parameters, ensuring output stability. The delay trigger module 15 has a built-in high-precision timing chip that works in conjunction with the trigger controller 26 to achieve millisecond-level delay adjustment, suitable for high-precision requirements.

[0038] To enhance the visualization of the control system, a power display module 1 is installed on the top of the chassis 20. This module is connected to the power supply 22 and the analog signal transmission control board 25, respectively, to display the current power status in real time. The power display module 1 is powered by 24V. VCC is connected to the positive terminal of the 24V power supply, GND is connected to the negative terminal, IN+ is the positive input signal, and IN- is the negative input signal. These terminals are connected to the positive and negative output control lines on the analog signal transmission control board 25, respectively.

[0039] It also includes a key switch 13 and an emergency stop switch 14, both mounted on the chassis 20 and connected to the power supply 22. Both are connected in series with the rocker switch 5 and are used for starting the control system and stopping it in an emergency, respectively, to ensure operational safety. The key switch 13 requires a key to be inserted and rotated to the start position for the system to be powered on. The key switch 13 provides two signals, connected in series in the analog signal transmission control board 25 circuit, and controls the entire laser output by breaking the circuit.

[0040] The emergency stop switch 14 cuts off power when pressed to prevent accidents. The emergency stop switch 14 is connected to the RST interface of the trigger controller 26. The RST interface is used to turn off the laser output. It is connected to the normally open line of the emergency stop switch 14. Pressing it turns off the laser output. When it is released, it is on the circuit. Pressing it turns it off.

[0041] The power display module 1, delay trigger module 15, light source, power supply 22, analog signal transmission control board 25, and trigger controller 26 in this embodiment adopt a modular and split design. If a module needs rework, only the corresponding module needs to be removed, reducing rework time. The modules are rationally laid out and easy to operate. The chassis 20 serves to secure the modules. The chassis 20 is made of high-strength aluminum alloy, which features high hardness, high strength, high durability, smooth surface, good texture, and good cold resistance, allowing for long-term use in high and low temperature environments. The various boards in the chassis 20 are fixed together with precision screws, ensuring structural stability and facilitating maintenance and replacement.

[0042] One or two sets of U-shaped handles 16 are symmetrically installed on the side wall of the chassis 20. The design is ergonomic, providing a comfortable grip and facilitating equipment movement. The bottom of the chassis 20 is equipped with anti-vibration feet 18, which are made of highly elastic material and can effectively reduce vibration noise during equipment operation, ensuring stable placement and safe operation.

[0043] The laser is controlled by a power supply 22, which supplies power to the light source module, power display module 1, debugging mode button switch 2, debugging mode voltage generator 3, debugging mode fan speed controller, working mode button switch 6, working mode voltage generator 7, working mode fan speed controller 8, key switch 13, emergency stop switch 14, delay trigger module 15, debugging mode fan drive board 23, working mode fan drive board 24, analog transmission control board 25, trigger controller 26, etc. Each light source outputs a fiber optic cable, which is then combined and spliced ​​by a combiner 21 to finally output a single fiber optic cable for high-power output.

[0044] Both the debug mode voltage generator 3 and the working mode voltage generator 7 support 12V and 24V power supply. The power supply interface GND / V+ is connected to the positive and negative terminals of the 12V power supply. The signal interface OUT / GND corresponds to the positive and negative terminals of one signal terminal on the analog transmission control board 25, and the two channels are controlled and output separately. The debug mode voltage generator 3 and the working mode voltage generator 7 are controlled by 0-5V analog signals. The analog transmission control board 25 converts the analog signals into electrical signals for control. The trigger controller 26 also uses electrical signals for triggering, which can achieve nanosecond-level response time. The delay trigger module 15 is linked with the trigger controller 26 to precisely control the laser emission through a preset delay time, ensuring accurate output every time.

[0045] Compared to existing technologies, this invention adopts an advanced technical architecture, resulting in a simpler and clearer overall wiring, significantly reducing installation and maintenance workload. Through the rational layout of each module, the system's response speed is significantly improved, reaching less than 5 microseconds, ensuring the laser is always in optimal working condition. Simultaneously, this invention is highly targeted, designed according to actual application needs, allowing for rapid adjustment of control parameters to achieve personalized control solutions. Furthermore, in terms of operation, it employs a simple and user-friendly interface, enabling users to complete control tasks with minimal effort, even those without professional technical backgrounds. In conclusion, this invention effectively solves many problems existing in current laser controllers, bringing a more efficient, precise, and convenient control solution to the laser application field, possessing broad market prospects and application value.
