Description

technical field [0001] The invention belongs to a semiconductor laser device, more specifically, the invention relates to an assembly and adjustment device for coupling multiple single-tube semiconductor lasers to a single-core optical fiber. Background technique [0002] The structural characteristics and light-emitting characteristics of semiconductor lasers determine that the light emitted by it has a large divergence angle and a narrow light-emitting area in the direction perpendicular to the active layer (commonly known as the fast axis), and has a large divergence angle in the direction parallel to the active layer (commonly known as the slow axis). With a smaller divergence angle and a larger light-emitting area, it is more widely used to couple semiconductor lasers into optical fibers. There are many methods for coupling a single-tube semiconductor laser to an optical fiber, such as direct coupling, ball lens coupling, aspheric lens coupling, and fast and slow axis c...
