ABSTRACT:
A layered semiconductor laser which has a multiplicity of thin film type layers of semiconductor diodes that are closely spaced such as to reduce phase differences between lasing layers or junctions in such a manner that the light emitting from all layers adds substantially in phase to provide a uniform phase front as the light leaves the layers of semiconductor material.
