Description

technical field [0001] The invention relates to the field of laser technology, in particular to a platform-type deflection-reflection single-tube semiconductor laser fiber coupling module. Background technique [0002] High-power semiconductor lasers have a series of advantages such as high output power, small size, light weight, long working life, and high electro-optical conversion efficiency, and have been widely used in various fields such as pumping solid-state lasers, direct material processing, communications, and medical treatment. However, because high-power semiconductor lasers also have problems such as poor beam quality, it is difficult to apply them in some occasions that require high beam quality. [0003] At present, the output power of commercially produced single-tube high-power semiconductor lasers has reached the order of 10W or more, but there is still a big gap from the needs of some practical applications. In order to further increase the output power ...
