ABSTRACT:
A semiconductor laser module has a semiconductor laser device; a package for housing the semiconductor laser device; a PBC fixed in the package for polarization-synthesizing two laser beams output from the semiconductor laser device; a depolarizing element fixed in the package for depolarizing a synthesizing light output from the PBC; and an optical fiber for receiving a light output from the depolarizing element.
