[0002] A slab amplifier, especially a slab laser amplifier, refers to a device in which the gain medium is in the form of a slab and the laser signal is amplified when passing through the medium.

[0014] A preferred technical solution is that a heat dissipation groove is provided inside the lens, and the heat dissipation groove is composed of an oblique groove and an annular groove. A heat-conducting copper ring is embedded in the annular groove, and a heat-conducting copper sheet 1 is embedded in the oblique groove. The heat dissipation groove does not extend to the middle of the lens, and the heat-conducting copper sheet 2 passes through the lens and the support shell in sequence and then extends outward.

[0033] like Figures 1 to 8 As shown, the present invention proposes a slat amplifier with three-dimensional graphene structure heat dissipation, comprising a base 1, a light shielding cover 2 covering the base 1, and a lens 3 and a light-transmitting panel 4 arranged in the base 1, the lens 3 is arranged on both sides of the light-transmitting panel 4, and a heat dissipation port 2 15 for heat dissipation is arranged in the base 1, the cross-section of the base 1 is U-shaped, and the heat dissipation port 2 15 is symmetrically arranged on the left and right sides of the base 1, and the inner end of the base 1 is connected to the outside through the heat dissipation port 2 15 on both sides;

[0034] The second heat dissipation opening 15 is in an inverted V-shaped structure, and the middle part of the second heat dissipation opening 15 is higher than the heights of both ends thereof;

[0035] The lower end of the inner side of the base 1 is connected downwardly through a plurality of air ports 12, the air ports 12 are arranged obliquely, and the lower side port of the air port 12 is larger than the upper side port thereof, and all the air ports 12 are connected to the air compressor through an air pipe 13, and the air compressor creates air flow to cool the inside of the base 1;

[0036] The slab amplifier mentioned in the background technology, although it has improved heat dissipation compared with the traditional rod-shaped laser medium, still has the problem of fixed structure and easy heat collection effect during laser conduction. Long-term high temperature not only affects the amplification effect of the laser, but also may cause the curvature of the lens surface to change, thereby affecting the actual use effect. The design of the heat dissipation port 2 15 in the present invention is an innovative solution to this technical problem. The heat dissipation port 2 15 adopts an inverted V-shaped structure, the height of the middle is higher than the height of the two ends. This design enables the heat dissipation port to form an efficient heat dissipation channel on the left and right sides of the base 1. When the laser amplifier is working, the heat generated will be guided to the heat dissipation port 2 with the air flow. 15, and due to its special shape design, it can accelerate the rise and discharge of hot air, thereby effectively reducing the temperature inside the base 1. This design not only improves the heat dissipation efficiency, but also avoids the circulation of hot air inside the base, reducing the occurrence of heat collection effect. In addition to directly solving the heat dissipation problem, the inverted V-shaped structure of the heat dissipation port 2 15 also brings other beneficial effects. First, it enhances the structural strength of the base 1, making the entire amplifier more stable and durable. Secondly, the inverted V-shaped structure visually forms a dynamic aesthetic and enhances the overall appearance of the product. In addition, this structure also helps to reduce the accumulation of dust and debris, keep the heat dissipation channel unobstructed, thereby extending the service life of the laser amplifier;

[0037] The air port 12 is another key design in the present invention, and has also effectively improved the heat dissipation problem mentioned in the background technology. The air port 12 is tilted, and the lower port is larger than the upper port. This design allows air to flow into the base 1 more smoothly and be connected to the air compressor through the air pipe 13 to form a forced air flow. The tilted setting of the air port 12 and the difference in port size not only increase the air flow rate, but also improve the uniformity of the air flow. When the air compressor is started, the air port 12 can quickly introduce cold air into the base 1, exchange with the hot air inside, and discharge it through the heat dissipation port 15. This design effectively reduces the base 1 The internal temperature avoids the performance degradation and damage of the laser amplifier caused by long-term high-temperature operation. In addition to the significant heat dissipation effect, the design of the air port 12 also brings other beneficial effects. First, the inclined air port design helps to prevent dust and moisture from entering the base 1, thereby protecting the internal lens 3 and light-transmitting panel 4 and other key components. Secondly, the connection between the air port 12 and the air compressor makes the entire heat dissipation system more intelligent and controllable. Users can adjust the power and working time of the air compressor according to actual needs to achieve the best heat dissipation effect. Finally, the design of the air port 12 also takes into account the convenience of maintenance, allowing users to operate more conveniently during cleaning and maintenance.

[0038] The lower port of the air port 12 is covered with a layer of filter cotton sheet 121, and the filter cotton sheet 121 is fixed to the outer side of the lower end of the base 1 through a filter screen 122. All the air ports 12 are arranged below the light-transmitting panel 4, and the width of the upper port of the air port 12 is smaller than the width of the light-transmitting panel 4.

[0039] In the slat amplifier of the three-dimensional graphene structure heat dissipation of the present invention, the design of the air port 12 not only focuses on the improvement of heat dissipation efficiency, but also fully considers the dustproof and self-cleaning functions. This innovation is reflected in the filter cotton sheet 121 covered by the lower port of the air port 12 and its fixing method. The filter cotton sheet 121 is firmly fixed to the outer side of the lower end of the base 1 through the filter screen 122. Such a design not only ensures the stability of the filter cotton sheet, but also facilitates subsequent replacement and maintenance. All air ports 12 are cleverly arranged below the light-transmitting panel 4, and the width of the upper port of the air port 12 is smaller than the width of the light-transmitting panel 4. Such a layout not only ensures the uniform distribution of the airflow, but also effectively avoids the airflow directly impacting the light-transmitting panel 4, thereby protecting the integrity of the optical element.

[0040] When the air compressor starts and blows the air flow strongly into the air port 12, the flow path of the air flow is carefully designed to achieve multiple effects. First, the air flow flows upward along the inclined direction of the air port 12, directly impacting the heat source inside the base 1, and takes away a large amount of heat through heat exchange, effectively reducing the temperature inside the base, providing a stable working environment for the laser amplifier. In this process, the rapid flow of the air flow also promotes the circulation of the air inside the base, further enhancing the heat dissipation effect;

[0041] At the same time, another part of the airflow flows out along the lower port of the air port 12. The design of this path is particularly ingenious. Since the filter cotton sheet 121 covers the lower port of the air port 12, when the airflow passes through, it not only takes away the heat on the filter cotton sheet, but also produces a "purge" effect. The force of the airflow is enough to blow off the dust and impurities attached to the surface of the filter cotton sheet 121, realizing the automatic cleaning function. This design greatly prolongs the service life of the filter cotton sheet and reduces the maintenance frequency. At the same time, it also ensures the quality of the airflow entering the base 1, avoiding dust pollution to the optical components and the heat dissipation system;

[0042] In addition, the design of the air port 12 also takes into account the convenience in actual use. Since the filter cotton sheet 121 and the filter screen 122 are both located on the outer side of the lower end of the base 1, the user does not need to disassemble the entire amplifier when replacing or cleaning the filter cotton sheet, which greatly simplifies the maintenance process. At the same time, the tilt setting of the air port 12 and the difference in port size also ensure that even in harsh working environments, efficient and stable heat dissipation performance can be maintained, providing reliable protection for the laser amplifier.

[0043] Furthermore, the lens 3 includes a supporting shell 31, a lens 32 and a heat-conducting member 33. The supporting shell 31 is sleeved outside the lens 32, and the supporting shell 31 is fixed in the base 1 through the heat-conducting member 33. Both sides of the base 1 are provided with heat dissipation openings 14 for the heat-conducting member 33 to pass through. Both ends of the heat-conducting member 33 extend outward through the heat dissipation openings 14 on both sides thereof, and protrude from the two side surfaces of the base 1. There is a gap between the heat-conducting member 33 and the heat dissipation openings 14. The heat-conducting member 33 is aligned with the lens 32, and the middle part of the heat-conducting member 33 has a notch for the laser to pass through.

[0044] First, the heat-conducting member 33 acts as a bridge between the lens 3 and the base 1, and is responsible for quickly conducting the heat generated by the lens 32 to the outside of the base. The two ends of the heat-conducting member 33 extend outward through the heat dissipation ports 14 on both sides thereof, and protrude from the two side surfaces of the base 1. This design not only increases the contact area between the heat-conducting member and the air, but also utilizes the natural convection and radiation of the air to accelerate the heat dissipation.

[0045] The gap design between the heat dissipation port 14 and the heat-conducting component 33 is another ingenious feature of this heat dissipation system. This gap ensures that the heat-conducting component will not interfere with other parts of the base when conducting heat to the outside of the base, thereby maintaining an unobstructed heat dissipation path. At the same time, the existence of the gap also facilitates rapid replacement or maintenance of the heat-conducting component when necessary, thereby improving the flexibility and maintainability of the entire system.

[0046] The middle of the heat-conducting member 33 has a notch for the laser to pass through. This design not only ensures the smooth transmission of the laser signal, but also avoids the interference of the heat-conducting member on the laser path. At the same time, the material selection of the heat-conducting member is also very important. Usually, materials with high thermal conductivity, such as copper, aluminum, etc., are used to ensure that the heat can be quickly and evenly conducted to the entire heat-conducting member and effectively dissipated into the air through the heat dissipation port 14.

[0047] In actual operation, when the laser signal is amplified by the lens 32, the lens absorbs part of the laser energy and converts it into heat energy. The heat is then transferred to the heat-conducting member 33 through the support shell 31, and then quickly transferred to both ends of the heat-conducting member, and dissipated into the air through the heat dissipation port 14. In this process, the open design of the heat dissipation port 14 allows the air to flow freely, further enhancing the heat dissipation effect.

[0048] In summary, the ingenious combination of the heat dissipation port 14 and the heat-conducting component 33 realizes rapid heat dissipation of the lens 3 through efficient heat conduction and air convection mechanisms, ensuring the stability and reliability of the laser amplifier under long-term high-power operation. This innovative design not only solves the problem of lens heat dissipation, but also provides a strong guarantee for the efficient operation of the entire laser amplifier.

[0049] Furthermore, the heat-conducting component 33 includes a heat-conducting copper ring 331, a heat-conducting copper sheet 1 332, a heat-conducting copper sheet 2 333 and a heat-conducting copper sheet 3 334. The heat-conducting copper sheet 1 332 is rotatably arrayed in the heat-conducting copper ring 331 and connected to the heat-conducting copper ring 331. The heat-conducting copper ring 331 is inserted into the heat dissipation port 1 14 through the heat-conducting copper sheet 2 333 arranged on both sides, and the heat-conducting copper sheet 2 333 extends out of the surface of the base 1. The heat-conducting copper sheet 334 is fixed to one end of the heat-conducting copper sheet 2 333 located on the outside of the base 1;

[0050] There is a gap between two adjacent heat-conducting copper sheets 1 332, and the heat-conducting copper ring 331, the heat-conducting copper sheet 1 332 and the heat-conducting copper sheet 2 333 are an integrated structure. In addition, a heat dissipation groove 321 is provided in the lens 32, and the heat dissipation groove 321 is composed of an oblique groove and an annular groove. The heat-conducting copper ring 331 is embedded in the annular groove, and the heat-conducting copper sheet 1 332 is embedded in the oblique groove. The heat dissipation groove 321 does not extend to the middle of the lens 32, and the heat-conducting copper sheet 2 333 sequentially penetrates the lens 32 and the support shell 31 and then extends outward;

[0051] The heat-conducting copper ring 331 is embedded in the annular groove in the lens 32 and is in close contact with the lens. Due to the high thermal conductivity of copper, the heat generated by the lens absorbing laser energy can be quickly transferred to the heat-conducting copper ring. The heat-conducting copper sheet 1 332 is rotated and arrayed in the heat-conducting copper ring and connected to the heat-conducting copper ring. This design not only increases the heat conduction area, but also enables the heat to be quickly dispersed and conducted between the heat-conducting copper ring and the heat-conducting copper sheet 1. The heat-conducting copper sheet 2 333 further transfers the heat on the heat-conducting copper ring and the heat-conducting copper sheet 1 to the heat dissipation port 14, and finally dissipates it into the air.

[0052] The rotating array design of the thermal conductive copper sheet 1 332 and the gap between two adjacent thermal conductive copper sheets 1 effectively increase the contact area with the air, thereby improving the heat dissipation efficiency. The thermal conductive copper sheet 2 333 extends out of the surface of the base 1, further increasing the heat dissipation area and accelerating the heat dissipation. The close connection and rotating array design of the thermal conductive copper ring 331 and the thermal conductive copper sheet 1 332 ensure the uniform distribution and rapid conduction of heat on the lens, avoiding the occurrence of local overheating. The extended design of the thermal conductive copper sheet 2 333 also helps to evenly distribute the heat to the outside of the base, thereby improving the overall heat dissipation effect.

[0053] In addition, a cavity 311 is provided in the support shell 31, and openings 312 are provided on both sides of the cavity 311. The openings 312 correspond to the second thermal conductive copper sheet 333. The second thermal conductive copper sheet 333 passes through the cavity 311 through the openings 312 and extends outward to the surface of the base 1. The cavity 311 is connected to all the openings 312.

[0054] A preferred technical solution is that an extension plate 11 is provided on the side of the base 1, and a corresponding extension plate 2 21 is provided on the shading cover 2. When the shading cover 2 is covered on the base 1, the extension plate 2 21 is abutted against the surface of the extension plate 1 11, and a rectangular long strip hole is formed between the extension plate 1 11 and the extension plate 2 21 for the laser to pass through.

[0055] The above description is only a preferred embodiment of the present invention, and therefore cannot be used to limit the scope of the present invention. That is, equivalent changes and modifications made according to the patent scope of the present invention and the contents of the specification should still fall within the scope of the present invention.
