Abstract
A laser module has a base portion having a metal holding portion; a laser light source fixed to the base portion; an optical outputting portion deriving the laser light from a collimating optical system out of the base portion. The collimating optical system includes an input lens receiving the laser light from the laser light source; and an output lens receiving the laser light from the input lens and outputting the laser light to the optical outputting portion, each located in order from the laser light source. The input lens is a convex lens fixed in a first cylinder body made of metal and welded to the holding portion. The output lens is a convex lens having a focal point length longer than that of the input lens and held by the holding member glued to the base portion.
