FIBER LASER DEVICE

摘要

A fiber laser device 1 includes: a pumping light source 10 that emits pumping light; an amplification optical fiber 30 that amplifies and emits signal light by the pumping light; a detector 71 that detects a power of stimulated Raman scattering light generated from the signal light propagated through the amplification optical fiber 30 or the signal light emitted from the amplification optical fiber 30 in preference to a power of the signal light; and a controller 80 that controls a power of the pumping light based on the power of the light detected by the detector 71.

1. A fiber laser device comprising:
a pumping light source that emits pumping light; an amplification optical fiber that amplifies and emits signal light of a single wavelength by the pumping light; a detector that detects a power of a wavelength component of stimulated Raman scattering light generated from the signal light propagated through the amplification optical fiber or the signal light emitted from the amplification optical fiber in preference to a power of a wavelength component of the signal light; and a controller that controls a power of the pumping light based on the power of the light detected by the detector.
