[0002] Solid-state blue laser is a laser that uses solid materials as gain medium and can emit blue light beams. Its working principle is based on stimulated radiation. The pump source excites the particles in the gain medium to reach a high energy state, thereby achieving laser output.

[0003] Existing solid-state blue light lasers often have poor heat dissipation efficiency when used for a long time. The thermal effect affects the performance of the laser, and the connecting harness cannot be quickly connected. When in use, the harness will be dragged due to the movement of the solid-state blue light laser, and the harness may easily fall off.

[0032] The present invention provides a solid blue laser, comprising a quick-detachable fixed-line installation component 1, the upper end outer surface of the quick-detachable fixed-line installation component 1 is detachably connected with a water circulation type thermal management component 2 for heat dissipation, the front end of the water circulation type thermal management component 2 is fixedly connected with a sliding self-cleaning laser head 3 for lens protection, the interior of the quick-detachable fixed-line installation component 1 is detachably connected with an aperture expansion mirror output component 4, a pump cavity component 5 and a total reflective mirror switch component 6 for solid blue laser emission, the aperture expansion mirror output component 4 is located on the left side of the pump cavity component 5, the total reflective mirror switch component 6 is located on the right side of the pump cavity component 5, and the quick-detachable fixed-line installation component 1 is connected to the outer surface of the upper end of the quick-detachable fixed-line installation component 1. It includes a slider fixing base 101, a side baffle 102, a sealing side plate 103, an internally threaded adjustment rod 104, an anti-slip adjustment button 105, a fixed line baffle 106 and a baffle groove 107. The water circulation thermal management component 2 includes a U-shaped heat conduction plate 201, a water circulation groove 202, a sealing baffle 203, a cooling plate 204, a transverse heat exchange turbofan 205, a heat dissipation fin 206 and a micro booster pump 207. The sliding self-cleaning laser end 3 includes a mounting panel 301, a rectangular groove 302, a threaded sliding rod 303, an internally threaded movable plate 304, a dual-lens module 305, a micro cleaning motor 306 and a sliding drive motor 307.

[0033] In an optional embodiment, the side baffles 102 on both sides of the slider fixing base 101 are aligned with the two sides of the U-shaped heat conductive plate 201 of the water circulation thermal management group 2. After the connection, the sealing side plates 103 on the side baffles 102 are squeezed to ensure the sealed connection between the slider fixing base 101 and the U-shaped heat conductive plate 201, thereby preventing external dust from corroding its internal components.

[0034] In an optional embodiment, the internal threaded adjustment rod 104 inside the slider fixed base 101 is rotated by holding the anti-slip adjustment button 105 at one end of the internal threaded adjustment rod 104. First, the internal threaded adjustment rod 104 engages with the thread inside the slider fixed base 101 to move the internal threaded adjustment rod 104 out from the inside. After moving to the specified position, the fixed wire baffle 106 on the outer wall of the internal threaded adjustment rod 104 limits the tail end of the wiring harness through the baffle slot 107 with a larger bottom and smaller top shape. After the limited installation, the anti-slip adjustment button 105 is held to rotate the internal threaded adjustment rod 104 in the opposite direction to move the positions of the internal threaded adjustment rod 104 and the anti-slip adjustment button 105.

[0035] In an optional embodiment, when in use, circulating cooling water is injected into the water circulation grooves 202 inside the U-shaped heat conductive plate 201 and the sealing baffle 203, and the heat generated by the solid blue light laser during operation is heat exchanged by the circulating cooling water. The heat after the heat exchange is transferred to the heat dissipation fins 206.

The refrigeration plate 204 generates a large amount of heat on its back when performing bottom surface cooling, and the heat is transferred to the heat dissipation fin 206. After the transfer, the horizontal heat exchange turbofan 205 on its top guides the external low-temperature air to the heat dissipation fin 206, and takes away the heat to cool it. When in use, the thermoelectric semiconductor refrigerator absorbs the heat in the cooling water, reduces the cooling water temperature and improves the heat dissipation effect.

[0037] In an optional embodiment, the sliding drive motor 307 on the back of the mounting panel 301 drives the threaded sliding rod 303 inside the rectangular slot 302, and the threaded sliding rod 303 is threadedly engaged with the internal threaded movable plate 304 to achieve lateral movement of the internal threaded movable plate 304. After the movement, the use status of the laser end can be adjusted, and the end protection work can be completed after stopping work.

[0038] In an optional embodiment, the internal thread movable plate 304 and the threaded sliding rod 303 are threadedly engaged to push the dual-lens module 305 to adjust the use position. After the micro-cleaning motor 306 on the dual-lens module 305 moves to the front of the inner end of the solid blue light laser, the micro-cleaning motor 306 is started to drive the cleaning brush head, thereby completing the dust cleaning work on the inner end of the solid blue light laser.

[0039] In an optional embodiment, the slider fixing base 101 is sealed and fixedly connected to both sides of the U-shaped heat conducting plate 201 through the sealing side plates 103 on both sides. After the connection, the water circulation slot 202 composed of the U-shaped heat conducting plate 201 and the sealing baffle 203 is filled with cooling circulating water, and the water flow is pushed by the micro booster pump 207. When in use, the connection sealing can be ensured and the heat dissipation effect can be changed by changing the water flow speed.

[0040] In an optional embodiment, the rear end of the mounting panel 301 is fixedly connected to the side baffle 102 at the front end of the slider fixing base 101, and a fixing groove with the same shape as the sliding drive motor 307 is opened in the middle of the front end side baffle 102. The sliding drive motor 307 is limitedly connected to the front end side baffle 102 through the fixing groove, and the driving end of the sliding drive motor 307 is threadedly engaged with the threaded sliding rod 303 inside the mounting panel 301. The sliding drive motor 307 is fixedly connected to the front end side baffle 102 which fits the size of the sliding drive motor 307, so as to avoid the occurrence of connection gaps.

[0041] This embodiment also discloses a method for using a solid blue laser, comprising the following steps:

[0042] Step 1: The solid blue laser power supply harness is limited by the baffle groove 107 in the middle of the wire fixing baffle 106, and the anti-slip adjustment knob 105 rotates the internal thread adjustment rod 104 to adjust the use position of the wire fixing baffle 106 to complete the fixing of the harness;

[0043] Step 2: When the solid blue laser is working, the circulating liquid inside the water circulation slot 202 is cooled by the cooling plate 204. The cooling plate 204 discharges the heat generated by the circulating liquid through the transverse heat exchange turbofan 205 and the heat dissipation fins 206. The low-temperature liquid completes the heat exchange and cooling work of the solid blue laser through the U-shaped heat conduction plate 201.

[0044] Step three: When the solid blue laser is working, the sliding drive motor 307 drives the threaded sliding rod 303 to engage with the internal threaded movable plate 304, thereby completing the adjustment of the use position of the dual-lens module 305 and moving the left side of the dual-lens module 305 to the middle. When the solid blue laser stops working, the sliding drive motor 307 drives the threaded sliding rod 303 in the reverse direction to move the right side of the dual-lens module 305 to the middle, completing the covering of the solid blue laser end, and the micro cleaning motor 306 can drive the internal cleaning brush head to complete the cleaning of the solid blue laser end.

[0045] Working principle: During installation, firstly, the side baffles 102 on both sides of the base 101 are fixed by the sliders and connected to the two sides of the U-shaped heat conducting plate 201 of the water circulation type thermal management group 2, and the anti-slip adjustment button 105 rotates the internal thread adjustment rod 104 to adjust the use position of the fixed wire baffle 106 to complete the fixation of the wire harness. When in use, the sliding drive motor 307 on the back of the installation panel 301 is started according to the use situation to drive the threaded sliding rod 303 inside the rectangular slot 302, and the threaded sliding rod 303 and the internal threaded movable plate 304 are threadedly engaged to realize the internal threaded movable plate 304. 04 moves horizontally, and after moving, the use status of the laser end can be adjusted. After stopping working, the micro cleaning motor 306 can be started to drive the cleaning brush head, so as to complete the dust cleaning work of the end inside the solid blue light laser. When the solid blue light laser works at high intensity, the cooling plate 204 cools the circulating liquid inside the water circulation slot 202. While cooling, the cooling plate 204 discharges the heat generated by it through the horizontal heat exchange turbofan 205 and the heat dissipation fins 206. The low-temperature liquid completes the heat exchange and cooling work of the solid blue light laser through the U-shaped heat conduction plate 201.
