Abstract

A fiber laser device includes: a first amplification optical fiber (61); a first FBG (51) and a second FBG (52) sandwiching the first amplification optical fiber (61); a second amplification optical fiber (62) disposed on the opposite side of the second FBG (52) from the first amplification optical fiber (61); a first pumping light source (11) that introduces pumping light into the first amplification optical fiber from the side of the first FBG (51); and a second pumping light source (12) that introduces pumping light into the second amplification optical fiber (62) from the opposite side from the second FBG (52), in which the concentration of an active element added to the core of the second amplification optical fiber (62) is higher than the concentration of an active element added to the core of the first amplification optical fiber (61), and part of the pumping light from the first pumping light source (11) passes through the first amplification optical fiber (61) and propagates to the second amplification optical fiber (62).
