[0002] Solid-state lasers are generally composed of laser working materials, pump sources, focusing cavities, and resonant cavity reflectors. The working material is the core of the laser, and is made of crystal or glass materials doped with metal ions that can produce stimulated emission. These metal ions have the characteristics of a wide effective absorption spectrum band, high fluorescence efficiency, long fluorescence lifetime, and narrow response spectrum lines, and are easy to produce population inversion and stimulated emission. With the continuous development of technology, solid-state lasers have made significant improvements in materials, structures, and pumping methods. Solid-state lasers are used in many key fields such as medicine, automobiles, aerospace, and military. Solid-state lasers have a very obvious thermal effect due to their large output energy and high peak power. However, due to the poor design of the cooling system, the heat generated by the laser cannot be effectively dissipated, causing the internal temperature of the laser to rise, affecting the stability of the laser wavelength, and further affecting the processing accuracy and efficiency, and also shortening the life of the laser.

The controller 8 compares the dust concentration with the preset value 10mg / m 3 In comparison, when the dust concentration exceeds 10 mg / m 3When the solid-state laser is still required to work in this environment, during the heat dissipation process, the controller 8 controls the baffle 2 to be closed and not opened to prevent dust from entering the shell 1 and causing damage to the internal components. The humidity sensor 7 is provided with a humidity-sensitive capacitor and a processing circuit. When the ambient humidity changes, the humidity-sensitive capacitor will absorb or release moisture, resulting in a change in the dielectric constant, thereby changing the capacitance value of the humidity-sensitive capacitor. The change in capacitance value is converted into an electrical signal output through the processing circuit. The humidity of the laser working environment is measured through calibration and measurement, and the information is transmitted to the controller 8. The controller 8 compares the received humidity information with the preset humidity range of 10% to 80%. When the humidity exceeds 80%, the baffle 2 is closed and not opened. At the same time, the power motor 24 drives the fan blades 10 to rotate to accelerate air circulation. When the humidity is lower than 10%, the pressurizing unit 29, the first nozzle 3 and the water tank 6 are connected through the water valve 28, the water in the water tank 6 enters the pressurizing unit 29 from the water inlet 34 through the water valve 28, the power motor 24 drives the rotating rod 33 to rotate, and the push rod 31 pushes the piston 30 forward under the drive of the rotating rod 33, so that the water entering the pressurizing unit 29 is squeezed out from the water outlet 35 and sprayed out from the first nozzle 3 in atomization, so as to humidify the working environment of the laser, realize the function of detecting the dust concentration and humidity of the working environment of the solid laser, solve the problems of output power reduction, equipment damage and aging caused by unsuitable working environment of the solid laser, ensure the transmission and quality of the laser, improve the performance and stability of the laser, and extend the service life of the laser.

[0037] Example 5: Please refer to Figure 1 , Figure 2 and Figure 3 , a solid laser with a rapid heat dissipation function, the heat dissipation component also includes an opening and closing module 13, the opening and closing module 13 includes: a pulley 14, a rotating shaft 15, a stopper 16, a baffle 2 and a fixer 17, the baffle 2 is connected to the rotating shaft 15 through the pulley 14, and the rotating shaft 15 is connected to the electric energy component through a connecting shaft; A baffle 2 is installed on the upper side of the outer wall of the shell 1, a limiter 16 is installed on the lower side of the outer wall of the baffle 2, a pulley 14 is installed on the lower side of the outer wall of the baffle 2, a rotating shaft 15 is installed on the right side of the outer wall of the pulley 14, and a fixer 17 is installed on the right side of the outer wall of the limiter 16.

[0038] Furthermore, as a precision optical device, the solid-state laser has a complex internal structure, involving knowledge in multiple fields such as optics, electronics and mechanical engineering. When performing maintenance, the disassembly work not only requires professional technicians, but also requires the use of professional tools and equipment to ensure the quality and safety of maintenance. The maintenance personnel need to have an in-depth understanding of the structure, working principle and possible dangers of the laser. The maintenance personnel need to inspect the internal components. The fixer 17 can be manually closed to manually open the baffle 2. The maintenance personnel can quickly check the fault inside the laser and replace it. During the operation of the solid-state laser, the upper part of the laser is opened by opening the opening and closing module 13 to connect with the air, so that the inside of the housing 1 is connected with the external environment, which is conducive to heat dissipation. If the heat dissipation of the solid-state laser is still not ideal after the baffle 2 is opened, a fan can be placed above the solid-state laser for auxiliary heat dissipation, thereby realizing the function of convenient maintenance of the solid-state laser, solving the additional problem of difficult and cumbersome disassembly when maintaining the solid-state laser, enabling maintenance personnel to easily access the internal components of the laser, improving the convenience of maintenance, and helping to ensure the long-term stable operation and performance optimization of the laser.

[0039] Working principle: The phase change heat accumulator 26 is provided with polyethylene material inside. When the temperature of the polyethylene material is within the range of 15℃~40℃, it will change from solid to liquid to absorb heat when the temperature rises, and will change from liquid to solid to release heat when the temperature drops. During the operation of the laser, the heat generated by the laser component is transported to the phase change heat accumulator 26 through the exchange tube 25. The phase change heat accumulator 26 absorbs the heat and maintains the temperature inside the shell 1 within the range of 15℃~35℃. When the temperature inside the shell 1 exceeds 35℃, the controller 8 receives the information transmitted by the temperature sensor 9 and transports the heat to the phase change heat accumulator 26 through the exchange tube 25. The phase change The heat accumulator 26 absorbs heat, causing its own temperature to rise. The control water valve 28 connects the cooling pipe 27 and the water tank 6 of the cooling module 12. The heat of the phase change heat accumulator 26 is heat-exchanged with the cooling water in the water tank 6 through the cooling pipe 27. The power motor 24 calls the electric energy stored in the battery 23 to drive the fan blades 10 to rotate, thereby accelerating the air circulation. At the same time, the controller 8 controls the fixer 17 to release the fixation of the baffle 2. The electric energy component drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the pulley 14 to rotate, thereby causing the baffle 2 to slide. After the baffle 2 slides to the position of the limiter 16, the upper part of the shell 1 is opened, thereby accelerating the air circulation inside the shell 1. During the operation of the solid laser, the laser component generates a large amount of heat, which is transported to the phase change heat storage device 26 through the exchange tube 25. The thermocouple 22 is composed of multiple groups of P-type semiconductor materials and N-type semiconductor materials connected in series. One end is close to the water tank 6 of the cooling module 12 as the cold end, and the other end is close to the heat collection module 11 as the hot end. The carriers of the P-type semiconductor material are holes, and the carriers of the N-type semiconductor are electrons. When there is a temperature difference between the cold end and the hot end, the carriers of the P-type and N-type semiconductor materials diffuse from the hot end to the cold end. This diffusion will eventually form a stable potential difference between the hot end and the cold end. The thermocouple 22 is connected to the battery 23 through a signal line to store the generated electrical energy in the battery 23; If there is dirt on the lens 5, when the laser emitted by the laser component passes through the lens, the dirt will absorb the laser energy and generate heat. The heat is transported to the heat energy collection module 11 through the exchange tube 25 arranged near the lens 5. Due to the increase in the heat source, the temperature difference between the hot end of the thermocouple 22 near the heat energy collection module 11 and the cold end near the water tank 6 is larger, which improves the efficiency of temperature difference power generation. Through the change in the power generation efficiency of the electric energy component, it is known that the heat accumulation inside the laser is aggravated. The controller 8 controls the water valve 28 to connect the pressurizing unit 29, the first nozzle 3 and the water tank 6 to humidify the working environment of the laser and control the humidity not to exceed 80%. At the same time, the power motor 24 drives the fan blade 10 to rotate to accelerate the air circulation for auxiliary heat dissipation. The lens 5 is cleaned regularly, and the cleaning agent stored in the cleaning box 18 is sprayed on the lens 5 through the second nozzle 21. The rotating gear 36 is driven to rotate by the power motor 24. The clamp 37 moves back and forth on the slide rail 38, and the brush head 19 supported by the clamp 37 cleans the lens 5. Before the solid-state laser works, the dust concentration and humidity of the laser working environment are detected by the dust sensor 4 and the humidity sensor 7 and transmitted to the controller 8. The controller 8 compares the dust concentration with the preset value 10mg / m 3 In comparison, when the dust concentration exceeds 10 mg / m 3When the solid-state laser is still required to work in this environment, during the heat dissipation process, the controller 8 controls the baffle 2 to close and not open to prevent dust from entering the shell 1 and causing damage to the internal components. The controller 8 compares the received humidity information with the preset humidity range of 10% to 80%. When the humidity exceeds 80%, the baffle 2 is closed and not opened. At the same time, the power motor 24 drives the fan blades 10 to rotate to accelerate air circulation. When the humidity is lower than 10%, the pressurizing unit 29, the first nozzle 3 and the water tank 6 are connected through the water valve 28. The water in the water tank 6 enters the pressurizing unit 29 from the water inlet 34 through the water valve 28. The power motor 24 drives the rotating rod 33 to rotate. The push rod 31 pushes the piston 30 forward under the drive of the rotating rod 33, and the water entering the pressurizing unit 29 is squeezed out from the water outlet 35 and sprayed out from the first nozzle 3 in atomization to humidify the working environment of the laser.
