Abstract:
1. A semiconductor laser module comprising: a semiconductor laser element for emitting a laser light whose cross-sectional shape at an emission end face is elliptical; an optical fiber arranged to receive the laser light from the semiconductor laser element; a package for housing the semiconductor laser element and the optical fiber; a first fastening means for fastening the optical fiber to the package; and a second fastening means for fastening the semiconductor laser element to the package, wherein the first fastening means fastens a tip side of the optical fiber to the package without restricting the optical fiber in a direction of a major axis of the elliptical shape of the laser light such that a minor axis of the elliptical shape of the laser light becomes parallel to a line connecting both fastening positions that is restricted by the first fastening means and fastens a rear of the optical fiber to the package such that the major axis of the elliptical shape of the laser light becomes parallel to a line connecting both fastening positions that is restricted by the first fastening means.
