ABSTRACT:
A phase-locked semiconductor laser array having a plurality of lasing regions includes phase-shifting means on the emitting surface thereof through which laser light is emitted. The phase-shifting means provide a phase shift for those laser beams passing therethrough so that the phases of all the emitted laser beams are substantially the same. The phase-shifting means include a coating on the emitting surface which has a spatially varying thickness in the lateral direction.
