ABSTRACT:
A laser module includes: one or more semiconductor laser elements which emit one or more divergent laser beams; one or more collimator lenses which collimate the one or more divergent laser beams; a condensing lens which condenses the one or more collimated laser beams, and make the one or more collimated laser beams converge at a convergence position; an optical fiber which is arranged in such a manner that the convergence position is located on the light-entrance end face; and a package which contains the one or more semiconductor laser elements and the one or more collimator lenses, does not contain the condensing lens and the light-entrance end face, and is hermetically sealed.
