PROBLEM TO BE SOLVED : To provide a fiber laser device that can emit a laser light with different wavelength from that of an incident laser light.
SOLUTION : The fiber laser device includes a core to which a laser light radiated from a laser diode 4 enters and rare earth ions are doped, and a fiber that energizes and emits the laser light with different wavelength from that of an incident laser light. The fiber is divided so that the divided fibers may be parallel to each other, and laser lights emitted from the respective fibers are reflected on reflection mirrors to enter to the fibers provided together.
