<p>A semiconductor laser module comprising a semiconductor laser element (2) having a first stripe (9) and a second stripe (10) formed spaced apart from each other and respectively emitting a first laser beam (K1) and a second laser beam (K2) from the end faces of the first stripe (9) and the second stripe (10), a first lens (4) divergently separating the first laser beam (K1) from the second laser beam (K2) emitted from the semiconductor element (2), a half-wave plate (6) for rotating 90 degrees the polarization plane of the first laser beam (K1), a polarization synthesis member (7) for synthesizing incident first laser beam (K1) and second laser beam (K2) for outputting, and an optical fiber (8) for receiving a laser beam outputted from the polarization synthesis member (7) for outputting to the outside.</p> |
