Description

Technical Field

[0001] The invention relates to the technical field of lasers, and in particular to a 505nm optical fiber beam splitting laser. Background Art

[0002] Optically pumped vertical external cavity surface emitting semiconductor lasers (OPSL) combine the advantages of traditional surface emitting semiconductor lasers and optically pumped solid-state lasers. They can obtain circular TEM00 modes close to the diffraction limit and generate power of several watts or even higher, achieving a perfect combination of high beam quality and high output power. In addition, vertical external cavity surface emitting semiconductor lasers can use mature quantum well energy band engineering to design the required wavelength, and the external cavity structure similar to solid-state lasers can also conveniently perform intracavity frequency doubling and mode locking operation, making it a new type of practical laser light source.

[0003] Gas lasers are large in size, consume a lot of power, and are difficult to maintain, which causes inconvenience in actual use. Therefore, most of the current genetic analyzers use solid-state lasers with fiber beam splitting transmission. Compared with gas lasers, solid-state lasers with fiber beam splitting transmission have many outstanding advantages: high conversion efficiency, wide coverage band, long service life, direct modulation, small size, light weight, low price, easy integration, etc., and have low threshold current density, good quantum effect, good temperature characteristics, high output power, good dynamic characteristics, long service life, and shorter lasing wavelength. However, the fixed structure of the solid-state laser with fiber beam splitting transmission and the genetic analyzer is very cumbersome, which is very inconvenient when the laser needs to be disassembled and replaced, and is not easy to maintain and use. Summary of the invention

[0017] The present invention will be further described below in conjunction with the accompanying drawings. It should be noted that this embodiment is based on the technical solution and provides a detailed implementation method and specific operation process, but the protection scope of the present invention is not limited to this embodiment.

[0018] This embodiment provides a 505nm fiber beam splitting laser, such as Figure 1-3 As shown, it includes a mounting plate 1 and a laser body 2, a fixing plate 3 is provided between the laser body 2 and the mounting plate 1, and the laser body 2 and the fixing plate 3 are fixedly connected; two L-shaped card plates 4 are fixedly provided on one side of the mounting plate 1 corresponding to the fixing plate 3, and the two L-shaped card plates 4 are symmetrical about the fixing plate 3 from top to bottom; the upper end and the lower end of the fixing plate 3 are detachably fixed in the space surrounded by the two L-shaped card plates 4 and the mounting plate 1; the vertical portions of the two L-shaped card plates 4 are provided with through holes, and the fixing plate 3 is provided with a limiting hole 6 corresponding to the position of the through hole, one end of the limiting rod 5 is fixedly connected to the limiting plate 7, and the other end passes through the through hole and is detachably inserted into the limiting hole 6.

[0019] During installation, first push the upper and lower ends of the fixing plate 3 fixedly connected to the laser body 2 from one end of the upper and lower L-shaped card plates 4 into the space enclosed by the upper and lower L-shaped card plates 4 and the mounting plate 1 along the length direction, so that the upper and lower ends of the fixing plate 3 are engaged and fixed with the L-shaped card plates 4. At this time, insert the other end of the limiting rod 5 through the through hole into the limiting hole 6, which can fix the relative position of the fixing plate 3 and the L-shaped card plate 4. When the laser body 2 needs to be disassembled, pull out the limiting plate 7 connected to the limiting rod 5 together, and then push the fixing plate 3 out along the length direction until it is separated from the L-shaped card plate 4.

[0020] Specifically, a plurality of through holes, limiting holes and limiting rods corresponding to the positions may be provided so as to be equidistantly arranged along the length direction of the L-shaped clamping plate 4 , the fixing plate 3 and the limiting plate 7 .

[0021] In this embodiment, a heat conducting plate 8 is fixedly installed in the laser body 2, one side of the heat conducting plate 8 contacts the surface of the electronic components in the laser body 2, and the other side is evenly and fixedly connected with a plurality of heat dissipation fins 9, one end of the heat dissipation fins 9 extends out of the laser body 2. The arrangement of the heat conducting plate 8 and the heat dissipation fins 9 can enhance the heat dissipation performance of the laser body 2.

[0022] More specifically, in this embodiment, the heat dissipation fin 9 is composed of a plurality of bent portions.

[0023] In this embodiment, wedge blocks 10 are respectively provided at the top and bottom of the fixing plate 3, and dovetail grooves 11 matching the wedge blocks 10 are provided at the corresponding sides of the horizontal portions of the two L-shaped clamping plates 4. The matching clamping of the wedge blocks 10 and the dovetail grooves 11 can make the upper and lower ends of the fixing plate 3 more stably and accurately clamped in the space surrounded by the two L-shaped clamping plates 4 and the mounting plate 1.

[0024] In this embodiment, a vertical rod 12 is fixedly provided on the outward side of the vertical portion of the two L-shaped clamping plates 4, and the end of the vertical rod 12 away from the L-shaped clamping plate 4 is rotatably connected to a positioning pressure plate 13 through a ball bearing. The inner side surface of the positioning pressure plate 13 can contact or separate from the outer side surface of the limit plate 7 by rotation, and when the inner side surface of the positioning pressure plate 13 contacts the outer side surface of the limit plate 7, the positioning pressure plate 13 exerts pressure on the limit plate 7.

[0025] After the laser body 2 is installed, the positioning pressure plate 13 is rotated to make its inner side contact with the outer side of the limit plate 7. At this time, the positioning pressure plate 13 exerts pressure on the limit plate 7, which can make the installation of the limit plate 7 more stable. When the laser body 2 needs to be disassembled, the positioning pressure plate 13 is unscrewed to separate it from the limit plate 7.

One end of the positioning rod 14 is fixedly connected to the pull plate 16, and the other end passes through the socket and can be detachably inserted into the positioning socket 15.

[0027] After the positioning plate 13 is rotated until it contacts the limit plate 7, the positioning rod 14 on the pull plate 16 is inserted into the positioning hole 15 of the limit plate 7 through the insertion hole of the positioning plate 13, which can fix the relative position of the positioning plate 13 and the limit plate 7. When the positioning plate 13 needs to be unscrewed, the pull plate 16 together with the positioning rod 14 is pulled out to unscrew the positioning plate 13.

[0028] Furthermore, in the present embodiment, a portion of the positioning rod 14 located between the pull plate 16 and the positioning pressure plate 13 is sleeved with a positioning spring 17, one end of the positioning spring 17 is fixedly connected to the pull plate 16, and the other end is fixedly connected to the positioning pressure plate 13. In order to make the relative positions of the pull plate 16, the positioning pressure plate 13 and the limit plate 7 more fixed, the positioning spring 17 is provided in the present embodiment. When the positioning rod 14 is inserted into the positioning socket 15 of the limit plate 7, the positioning spring 17 pulls the pull plate 16, so that the pull plate 16 is not easily separated from the positioning pressure plate and the limit plate. Since the positioning spring 17 can be deformed, it will not hinder the removal of the pull plate 16 and the positioning rod 14.
