Figure 3 A cross-sectional view of a multi-wavelength solid laser provided by an embodiment of the present application. Figure 6 An exploded view of a light combining component provided by an embodiment of the present application. As Figures 1 to 3 , Figure 6 shown, an embodiment of the present application provides a multi-wavelength solid laser, including a red light component 100, a blue light component 200, a first total reflector 300, a light combining component 400, a first housing 500, and a second housing 600. Among them, the red light component 100 is used to emit red laser light, the blue light component 200 is used to emit blue laser light, the first total reflector 300 is located on the optical path of the blue laser light emitted by the blue light component 200, and the first total reflector 300 is used to reflect the blue laser light. The light combining component 400 is used for the red laser light to pass through and reflect the blue laser light that has passed through the first total reflector 300. The first housing 500 is provided with a receiving cavity 511, and the red light component 100 is installed in the receiving cavity 511. The second housing 600 is provided with a mounting groove 601, and both the blue light component 200 and the first total reflector 300 are fixed in the mounting groove 601. The light combining component 400 is installed on the second housing 600.

[0041] Specifically, the red light component 100 includes a pump source 110 and a mounting base 120. The pump source 110 is installed on the mounting base 120 and is disposed in the receiving cavity 511 after installation. The blue light component 200 includes a blue light diode 210 and a fixing base 220. After the blue light diode 210 is fixed on the fixing base 220, it is installed in the mounting groove 601 of the second housing 600 together. The pump source 110 emits red laser light, and the blue light diode 210 emits blue laser light. The first total reflector 300 is located on the optical path of the blue laser light emitted by the blue light component 200 and is used to reflect the blue laser light. For example, the red laser light emitted by the pump source 110 and the blue laser light emitted by the blue light diode 210 are parallel in the vertical plane. The light combining component 400 can allow the red laser light to pass through and reflect the blue laser light that has passed through the first total reflector 300. The light combining component 400 is installed on the upper top surface of the second housing 600 (see Figure 2 ), and the first housing 500 shields the light combining component 400. In particular, the pump source 110, the working medium, and the optical resonator on the red light component 100 cooperate to emit red laser light that meets the requirements. The red laser light emitted by the red light component 100 passes through the light combining component 400 and is used for marking products made of metal materials. The blue light diode on the blue light component 200 emits blue laser light. The blue laser light emitted by the blue light component 200 is reflected by the first total reflector 300 to the light combining component 400, and the light combining component 400 further reflects and emits the blue laser light for marking products made of wood.

[0042] It should be noted that through the first total reflection mirror 300 and the light combining component 400, the emission of red laser and blue laser can be completed, solving the problem of needing to replace the laser, making the marking process more simple and efficient, and improving the efficiency and quality of the marking operation.

[0043] Figure 4 The structural schematic diagram of a first half shell provided by an embodiment of the present application. Figure 5 The structural schematic diagram of a second half shell provided by an embodiment of the present application, as Figure 4 and Figure 5 shown, in some embodiments, the first housing includes a first half shell 510 and a second half shell 520. Among them, the first half shell 510 is provided with a receiving cavity 511, the second half shell 520 is spliced with the first half shell 510, and both the second half shell 520 and the first half shell 510 are fixed to the second housing 600.

[0044] Specifically, the first half shell 510 is provided with a receiving cavity 511 for receiving the red light component 100. The second half shell 520 is spliced with the first half shell 510 to form a complete first housing 500. For example, the red light component 100 is installed in the receiving cavity 511 of the first half shell 510, and then the first half shell 510 and the second half shell 520 are respectively fixed to the second housing 600 to ensure the stability and fixity of the first housing 500. The second half shell 520 is used to cover the light combining component 400.

[0045] Since the second half shell 520 is spliced with the first half shell 510 to form the first housing 500, the first housing 500 is simple to load and unload. At the same time, the first half shell 510 houses the red light component 100, and the second half shell 520 covers the light combining component 400, reducing the risk of mutual influence between the red laser and the blue laser. When internal components need to be repaired or replaced, it can be quickly disassembled and reassembled, improving the repair efficiency.

[0046] In some embodiments, the second half shell 520 is provided with a light outlet 521 and a covering cavity 522. The light outlet 521 is communicated with the covering cavity 522. The light combining component 400 protrudes from the second housing 600, and the covering cavity 522 is used to cover the light combining component 400. For example, both the blue laser and the red laser are emitted from the light outlet 521. The light combining component 400 is located in the covering cavity 522. The red laser passes through the light combining component 400, and the blue laser reflected by the first total reflection mirror 300 is reflected, thereby realizing different usage requirements of the red laser and the blue laser. The light combining component 400 is located in the covering cavity 522. Through the covering cavity 522, the interference of the red laser when the blue laser is emitted can be effectively isolated, improving the purity of the optical path.

[0047] Figure 6 The exploded view of a light combining component provided by an embodiment of the present application, as Figure 6As shown, the light combining component 400 includes a light combining lens holder 410, a light combining lens 420, and a reflective film 430. Among them, the light combining lens holder 410 has a mounting portion 411, and the mounting portion 411 is provided with a light transmission hole. The light combining lens holder 410 is fixed to the second housing 600. The light combining lens 420 is mounted on the mounting portion 411, and the reflective film 430 is fixed to the light combining lens 420. The reflective film 430 and the mounting portion 411 are respectively located on both sides of the light combining lens 420. The blue laser emitted by the blue light component 200 is transmitted from the light transmission hole to the reflective film 430.

[0048] Specifically, the mounting portion 411 is provided with a light transmission hole, and the light transmission hole is perpendicular to the top surface of the second housing 600 (see Figure 2 ). The blue laser emitted by the blue light component 200 is transmitted to the light transmission hole after passing through the first total reflection mirror 300. The reflective film 430 is fixed to the side of the light transmission hole close to the second half housing 520. The blue laser is then emitted from the light outlet 521 after being reflected by the reflective film 430. The mounting portion 411 protrudes from the second housing 600, and the side of the mounting portion 411 away from the second housing 600 is inclined. The inclined end surface fixes the light combining lens 420 and the reflective film 430. The reflective film 430 is fixed to the light combining lens 420. At the same time, the reflective film 430 and the mounting portion 411 are respectively located on both sides of the light combining lens 420. Among them, the reflective film 430 is arranged in parallel with the first total reflection mirror 300.

[0049] By reasonably setting the positions and angles of the light combining lens 420 and the reflective film 430, the optimization of the laser can be achieved, so as to meet the usage requirements of the red laser and the blue laser. The fixation of the light combining lens holder 410 to the second housing 600 improves the reliability of the multi-wavelength solid-state laser.

[0050] In some embodiments, the light combining component 400 further includes a red laser antireflection film 440, and the mounting portion 411, the red laser antireflection film 440, and the light combining lens 420 are fixed in sequence.

[0051] Specifically, the red laser antireflection film 440 and the light combining lens 420 are sequentially fixed on the mounting portion 411 of the light combining lens holder 410. For example, epoxy glue is used to fix the red laser antireflection film 440, the light combining lens 420, and the reflective film 430 on the mounting portion 411. Among them, the laser antireflection film 440 can increase the transmittance of the red laser on the light combining lens 420, improve the transmittance of the red laser, and improve the utilization efficiency of the red laser. In particular, the reflective film 430 is arranged in parallel with the first total reflection mirror 300. The angle between the first total reflection mirror 300 and the blue laser emitted by the blue light component 200 is 45 degrees in the vertical plane, which improves the transmission accuracy of the blue laser. The cooperation of the reflective film 430 and the first total reflection mirror 300 can enhance the emission effect of the blue laser.

[0052] In some embodiments, both the first housing 500 and the second housing 600 are provided with mounting holes 701. The multi-wavelength solid-state laser includes a fastener that passes through the mounting holes 701 to fix the first housing 500 and the second housing 600. Through the mounting holes 701 and the fastener, the first housing 500 and the second housing 600 are fixed. For example, the fastener is a screw or a bolt. The screw or the bolt is passed through the mounting holes 701 on the first housing 500 and the second housing 600 and tightened, so that the first housing 500 and the second housing 600 are fixed.

[0053] By providing the mounting holes 701 on the first housing 500 and the second housing 600 and using the fastener to pass through the mounting holes 701, the overall mounting stability is improved, which is more convenient when adjusting or maintaining the device, saving time costs.

[0054] In some embodiments, the first housing 500 is provided with a perforation 512, and the perforation 512 communicates with the accommodating cavity 511.

[0055] Specifically, the shape and size of the first housing 500 can accommodate the red light component 100. The perforation 512 is provided on the first housing 500. The perforation 512 is provided to allow the laser emitted from the pump source 110 to pass through and be transmitted to the light combining component 400. By providing the perforation 512, the laser passes through the perforation 512, optimizing the laser transmission efficiency and reducing energy dissipation.

[0056] It should be noted that, according to specific application requirements, the periphery of the perforation 512 is sealed, filled or otherwise treated to prevent other external substances from entering the interior of the housing.

[0057] In some embodiments, the mounting groove 601 is located on the side of the second housing 600 away from the first housing 500.

[0058] Specifically, the mounting groove 601 is provided on the second housing 600. The mounting groove 601 is located on the side of the second housing 600 away from the first housing 500, that is, the opposite side of the first housing 500. After the blue light component 200 and the first total reflection mirror 300 are installed in the mounting groove 601, a protective plate is provided outside the mounting groove 601.

[0059] In some embodiments, both the first housing 500 and the second housing 600 are provided with heat conduction grooves 702. For example, the heat conduction grooves 702 can be formed by a plurality of fins spaced apart, thereby enhancing the heat dissipation inside the housing, improving the heat conduction efficiency, and accelerating the heat dissipation. The heat conduction grooves 702 cooperate with heat sinks, fans or other heat dissipation devices to form a complete thermal management system.
