Summary:A semiconductor laser module 1 is mainly composed of a package 3, a semiconductor laser 5, lenses 7, 9, 13, reflecting mirrors 11, an optical fiber 15, and the like. The package 3 is composed of a bottom part and side surfaces 19a, 19b. The side surfaces 19a, 19b stand erect approximately vertical to the bottom part of the package. In the semiconductor laser module 1, a plurality of semiconductor laser installation surfaces 17 are formed in a step-like shape. On each semiconductor laser installation surface 17, a semiconductor laser 5 is installed. A lens 7 is arranged at the anterior (in the emission direction) of the semiconductor laser 5. Moreover, a lens 9 is arranged further to the anterior. A reflecting mirror 11 is fixed to the side surface 19a, which is provided facing the emission direction of the semiconductor laser 5.
