ABSTRACT:
A semiconductor laser device includes semiconductor layers including an active layer and cladding layers sandwiching the active layer and current injecting structure for regulating a region in the active layer into which current is injected. A light confinement coefficient in the current injection region perpendicular to the active layer is smaller than a light confinement coefficient in the same direction of a saturable absorption region. The function of the saturable absorption region is enhanced and pulsation oscillation can be produced at a high power light output.
