Abstract

A fiber laser device (1) includes: a first pumping light source (12) that emits first pumping light; a first amplification optical fiber (11) to which an active element is added, and which absorbs the first pumping light and amplifies and emits light having a first wavelength; a second amplification optical fiber (21) to which an active element that is the same as the active element added to the first amplification optical fiber (11) is added, and which absorbs the light having the first wavelength and amplifies and emits light having a second wavelength; combiners (31) and (32); and a light reduction unit (60) that is provided on each of the optical paths between the combiners (31) and (32) and the first amplification optical fiber (11), transmits light from the first amplification optical fiber (11), and suppresses transmission of light from the combiners (31) and (32).
