Light path beam combining and optical fiber coupling device of spatial light laser

Abstract

The invention provides a light path beam combining and optical fiber coupling device of a spatial light laser. A system comprises two parts, namely a laser beam combining module and an optical fiber coupling module; the laser beam combining module comprises a cage type coaxial system and an optical system; the cage type coaxial system is used for fixing an exciter and an optical lens; the optical system is used for completing laser beam combination; and the optical fiber coupling module comprises an optical fiber coupler, a five-axis optical adjusting frame, a displacement table, an optical fiber and the like. The two lasers are fixed through the cage type coaxial system, the optical axes of the two laser beams are parallel, the first laser beam turns to reach the second beam combiner after passing through the first reflector, and the second laser beam directly reaches the second beam combiner to be combined with the first laser beam; and the combined laser is subjected to fine light path adjustment in a cage type system through a collimator and then is coupled into an optical fiber through an optical fiber coupler.
