ABSTRACT:
To provide a semiconductor laser device which has no ripple and can afford better FFP having a pattern near a Gaussian distribution upon operation at the high output, the semiconductor laser comprising a laminate structure in which a first conductive type semiconductor layer, an active layer and a second conductive type semiconductor layer different from the first conductive type are laminated in this order, the laminate structure having a waveguide region to guide a light and resonator planes for laser oscillation on both ends, characterized in that the laminate structure has a non-resonator plane on one end side and the non-resonator plane is covered with a shading layer.
