Abstract
A semiconductor laser module includes a casing defining a chamber, light-emitting means fixed to the casing in the chamber, and a fiber optic connector installed so as to communicate the chamber of the casing to outside. The light-emitting means is fixed to the casing by means of a heat sink. The light-emitting means includes a semiconductor chip mounted on the heat sink for generating laser light, a current supply means arranged near the semiconductor chip on the heat sink, and a collimator lens supported by the heat sink so as to oppose the semiconductor chip.
