Description

technical field [0001] The invention relates to a semiconductor laser light source, in particular to the optical fiber coupling technology of the semiconductor laser. Background technique [0002] Semiconductor laser is the most important type of laser in practical use. It has the advantages of small size, long life, reliable operation, and low power consumption. It is used in laser communication, optical storage, optical gyroscope, laser printing, ranging, and radar. Widely, semiconductor lasers (LDs) are often used as light sources in laser displays or other occasions that require high-brightness and high-beam quality lasers, because semiconductor lasers have the problem that the output light is a divergent beam and the power density is relatively low. Lasers often cannot meet the requirements of laser displays for light sources. In practical applications, it is often necessary to couple the output light of multiple semiconductor lasers before outputting. At present, the...
