ABSTRACT:
In a semiconductor laser device wherein the laser beam emitted from an output end face of a semiconductor laser having antireflection coating for the opposite output end faces thereof is returned back to the output end face to induce self-coupling effects of the laser beam, the polarization characteristics of the output beam from the semiconductor laser are changed by controlling the polarization characteristics of the return beam.
