The semiconductor laser module

The utility model relates to a semiconductor laser module (1). The semiconductor laser module (1) is mainly composed of a packaging member (3), semiconductor lasers (5), lenses (7,9 and 13), a reflector (11), a fiber (15) and the like. The packaging member (3) is composed of a bottom and side surfaces (19a and 19b). The side surfaces (19a and 19b) are erected vertically substantially relative to the bottom of the packaging member (3). In the semiconductor laser module (1), a plurality of semiconductor laser arrangement surfaces (17) are stepped. The semiconductor laser (5) is arranged on the semiconductor laser arrangement surface (17). The lens (7) is arranged in front (in the emission direction) of the semiconductor laser (5). In addition, the lens (9) is arranged in front further. The reflector (11) is fixed on the side surface (19a) on the side surface (19a) arranged opposite to the emission direction of the semiconductor laser (5).
