Abstract
A semiconductor laser module includes a single semiconductor laser device having a first light emitting stripe and at least one other light emitting stripe which are aligned to respectively emit a first laser beam and at least one other laser beam through one edge surface. It also includes a first lens positioned so that the first laser beam and the at least one other laser beam emitted from the semiconductor laser device are incident thereon, the first lens configured to separate the first laser beam and the at least one other laser beam. A beam synthesizing member is included and has a first input part on which the first laser beam is incident, at least one other input part on which the at least one other laser beam is incident, and an output part from which the first laser beam emerging from the first input part and the at least one other laser beam emerging from the at least one other input part are multiplexed and emitted as a multiplexed laser beam. An optical fiber is positioned to receive the multiplexed laser beam therein.
