Abstract
Embodiments of the present application provide a laser light source and a laser projection device. The laser light source includes a laser assembly and a light combination mirror assembly. The laser assembly includes at least a laser, a light emitting surface of the laser has a plurality of light emitting regions, and beams emitted from different ones of the plurality of light emitting regions are in different colors. The light combination mirror assembly includes a plurality of mirrors that are sequentially arranged along an optical transmission path of the laser, with each of the mirrors corresponding to one of the light emitting regions. The light combination mirror assembly is used to converge the beams in different colors emitted from the laser to form a white beam.
