Description

Technical Field

[0001] The utility model relates to the field of optical fiber laser detection, in particular to an integrated platform for production and testing of optical fiber lasers. Background Art

[0002] Fiber laser is a special laser that uses glass fiber doped with rare earth elements as a gain medium to generate laser output. Compared with traditional solid lasers and gas lasers, fiber lasers have higher energy conversion efficiency, more compact structure, higher reliability, and are suitable for mass production. Due to the needs of industrial production, lasers are developing towards high output power, which will inevitably increase the size of the laser and reduce the heat dissipation efficiency. In the prior art, in order to reduce the size of the laser and ensure the heat dissipation effect, components such as pump light sources, optical fiber components, and power components are often installed on both sides of the water cooling plate.

[0003] In the prior art, the fiber laser to be assembled or tested is generally mounted horizontally on a support frame by bolts for assembly and testing. During assembly, the fiber laser to be assembled needs to be manually flipped over to complete double-sided assembly. When testing the fiber laser, the entire laser to be tested needs to be scanned by a manual handheld infrared imager. In order to perform light leakage detection on both sides of the laser, it is also necessary to disassemble and assemble it twice.

[0004] It can be seen that when the above technical solution is used to produce and test double-sided fiber lasers, secondary disassembly and assembly are required, which is inefficient and unsafe, increasing the risk of damage to the lasers to be assembled or tested. Utility Model Content

[0011] Furthermore, the mounting part includes an adjustment frame and a telescopic rod, the adjustment frame is movably arranged at the bottom of the protective cover, the telescopic rod is arranged on the upper part of the adjustment frame, and the telescopic rod is connected to the laser output head through a mounting ring.
