Description
technical field [0001] The invention relates to the field of multi-bundle fiber laser synthesis, in particular to a fiber laser array bundle and optical axis control device. Background technique [0002] Fiber laser research and development has a low threshold, good beam quality and wide application value, so it has developed rapidly in recent years. The single-fiber power is limited by physical factors and has a certain upper limit. For this reason, it is an effective way to increase the output power to combine multiple optical fibers. However, the optical axis consistency of existing multi-channel optical fibers is poor after synthesis. Contents of the invention [0003] In view of the above-mentioned shortcomings in the prior art, the present invention provides a fiber laser array bundle and optical axis control device that solves the problem of poor consistency of the optical axes of multi-channel optical fiber synthesis. [0004] In order to achieve the purpose of ...
