PROBLEM TO BE SOLVED: To provide a fiber laser of miniaturized, and high output linear polarized.SOLUTION: A fiber laser includes: a seed light source part which generates seed light; a preamplifier which amplifies the seed light radiated from the seed light source part; a polarization part which makes seed wavelength of the emitted light from the preamplifier penetrate, and maintains linear polarization of the emitted light while giving an absorption feature around the seed wavelength; and a fiber amplifier which amplifies intensity of signal light entered from the polarization part by an input of excitation light. |
