Abstract
A semiconductor laser module includes a semiconductor laser chip, a first collimator element, and a package. The package includes: a body having a bottom and a top with an opening; a cap member; and a window member. The semiconductor laser chip has a light-emitting point for emitting laser light. The semiconductor laser chip is located on the bottom so as to emit the laser light in a direction parallel to the principal surface of the bottom. The laser light has a greater divergence angle along the first axis than a divergence angle along a second axis perpendicular to the first axis. The first collimator element includes a concave mirror surface. The mirror surface reflects the laser light toward the opening, and reduces the divergence angle of the laser light along the first axis.
