Abstract
A semiconductor laser moduleis mainly composed of a package, a semiconductor laser, lenses, reflecting mirrors, an optical fiber, and the like. The packageis composed of a bottom part and side surfaces. The side surfacesstand erect approximately vertical to the bottom part of the package. In the semiconductor laser module, a plurality of semiconductor laser installation surfacesare formed in a step-like shape. On each semiconductor laser installation surface, a semiconductor laseris installed. A lensis arranged at the anterior (in the emission direction) of the semiconductor laser. Moreover, a lensis arranged further to the anterior. A reflecting mirroris fixed to the side surface, which is provided facing the emission direction of the semiconductor laser.
