摘要：

A semiconductor laser apparatus comprising: a semiconductor laser array device in which a plurality of laser operation areas are disposed in a parallel manner to attain optical phase coupling therebetween and laser lights are propagated with a 180 DEG phase shift therebetween in the adjacent laser operation areas, resulting in a far-field pattern having a peak in each of the two different directions of the emission of said laser beams therefrom, and a stem containing the semiconductor laser array device therein in such a manner that one of the the laser lights from the semiconductor laser array device is blocked with the inner wall of the stem and the other laser beam passes outside of the stem.
