ABSTRACT:
A semiconductor laser apparatus according to an exemplary embodiment of the present invention is provided. For example, the apparatus may include a single or a plurality of stacked-array laser diodes, first beam compressors, and a separating optical device separating the group of laser beams into subgroups of laser beams in a first direction, and deflecting the subgroups of laser beams so that the subgroups of laser beams approach in the first direction and recede from one another in a second direction. In addition, a collimating optical device may be provided which is adapted to deflect the subgroups of laser beams in the first and second directions by the same angles. Further, a beam converter may be included which divides each subgroup of laser beams and turning the axis thereof, and second beam compressors and a group of cylindrical lenses can be provided that can make the angle of divergence in the first direction close to the angle of divergence in the second direction.
