ABSTRACT:
A semiconductor laser includes a semiconductor laser chip stack having active layers formed substantially in the central portion thereof in the stacking direction and a pair of opposed reflecting surfaces formed at both ends of the active layers. A convex lens of a light transmissible material fixedly attached to a partially light transmissible reflecting surface of the pair of reflecting surfaces and adapted for converging a laser beam emitted from the partially light transmissible reflecting surface.
