Description

technical field [0001] The invention relates to a coupling device, in particular to a coupling device which is easy to operate and easy to use and can improve the welding efficiency of the first lens in a laser module. Background technique [0002] There are various manufacturing techniques of semiconductor lasers at present, mainly adopting the mode of welding and fixing the second lens after the first lens is welded. Since the welding position and coupling efficiency of the first lens will directly affect the final power of the semiconductor laser, the welding and fixing of the first lens is a very critical step in the process of manufacturing the semiconductor laser module. At present, when welding the first lens of the laser, beam analyzers are mostly used for optical path coupling. However, due to the relatively large light receiving surface of the beam analyzer, the power coupling is not very accurate, which reduces the final coupling power of the module. It affects t...

Problems solved by technology

At present, when welding the first lens of the laser, beam analyzers are mostly used for optical path coupling. However, due to the relatively large light receiving surface of the beam analyzer, the power coupling is not very accurate, which reduces the final coupling power of the module. It affects the performance and application range of the semiconductor laser module; at the same time, this method requires a long coupling time, which reduces production efficiency; and it is difficult to correct the welding offset, which brings some inconvenience to the subsequent welding work
