Document Type and Number:
WIPO Patent Application WO/2019/240171
Kind Code:
A1
Abstract:
The purpose of the present invention is to realize a fiber laser system in which failure due to Stokes oscillation is less likely to occur. This invention is provided with: a plurality of fiber laser units (FLU1-FLU7); a combiner OC for combining the laser light generated in each of the fiber laser units (FLU1-FLU7); and a control unit (C) for controlling the size of drive currents (I1-I7) fed to excitation light sources (PS1-PS6) included in the fiber laser units (FLU1-FLU7).
