ABSTRACT:
This invention has as its object to provide a solid-state laser device which can supply a laser beam pumped by a solid-state laser medium from the distal end of an optical fiber. In order to achieve this object, the solid-state laser device includes a solid-state laser device main body incorporating a semiconductor laser and a first optical system for shaping a first laser beam emitted from the semiconductor laser; an optical fiber cable connected to the solid-state laser device main body and accommodating an optical fiber for guiding the first laser beam shaped by the first optical system; and a solid-state laser medium which is incorporated in the distal end portion, at the light exit side, of the optical fiber cable, and outputs a second laser beam by generating the first laser beam.
