ABSTRACT:
A semiconductor laser device having an oscillator for use in a light source containing therein a two- or three-dimensional integrated circuit semiconductor laser element. The laser device comprises a base plate having a top surface, a mask layer having a predetermined pattern provided on the top surface of the base plate, a recessed portion formed by etching the base plate through the pattern of the mask layer, a projecting portion of the mask layer extending over a part of the recessed portion, and a semiconductor laser chip having a side surface or side surfaces emitting a light beam therefrom. The light beam emitted from the side surface of the semiconductor laser chip returns after being reflected by a part of the recessed portion and a part of the projecting portion. In an alternative embodiment, the light beam emitted from the side surface of the semiconductor laser chip is reflected by the inclined plane of the recessed portion and passes through a lens means to produce an output light beam.
