ABSTRACT:
A semiconductor laser device includes at least two semiconductor laser elements emitting a plurality of laser beams from the front and rear facets, a light guide layer which guides the respective laser beams emitted from the rear facets and converts the wave fronts of the beams while guiding them to form separated beams, and a plurality of photodetectors which detect the converted wave fronts converted to monitor the intensities of laser beams emitted from the front facets.
