Abstract
The present invention provides a semiconductor laser module in which a coupling efficiency does not easily vary even though a displacement amount varies by the effect of welding. The semiconductor laser module comprises: a semiconductor laser elementfor emitting a laser light whose cross-sectional shape at an emission end face is elliptical; an optical fiberarranged to receive the laser light from the semiconductor laser element; a packagefor housing the semiconductor laser elementand the optical fiber; a first fastening meansfor fastening the optical fiberto the package; and a second fastening meansfor fastening the semiconductor laser elementto the package, wherein the semiconductor laser elementand the optical fiberare fastened such that a minor axis of the elliptical shape of the laser light becomes parallel to a line connecting both ends of the optical fiber, said both ends being restricted by the first fastening means
