ABSTRACT:
A laser module includes: a chassis having a light-output window from which one or more laser beams are outputted; a hermetically sealed package which is fixed to the chassis; one or more semiconductor laser elements which are arranged in the hermetically sealed package, and emit the one or more laser beams; a transparent member which is arranged to cover the light-output window; an optical fiber which has a light-entrance end face, and is arranged outside the chassis so that the light-entrance end face is in contact with the transparent member; and an optical condensing system which is arranged inside the chassis, and makes the one or more laser beams pass through the transparent member and be condensed on the light-entrance end face. The transparent member and the optical fiber are detachably attached to the chassis.
