PROBLEM TO BE SOLVED : To provide stable laser equipment that prevents excitation light source damage due to oscillated laser beams. SOLUTION : This fiber laser equipment comprises an excitation light source, a fiber to which rare-earth elements have been added, and a resonator. This equipment has an excitation light source protection unit without an isolator function between the excitation light source and the resonator to prevent laser beams generated by the resonator from entering the excitation light source, by a method selected from at least one of the four methods, absorption, reflection, scattering and branching.
