Abstract
An object of the present invention is to provide an optical multiplexer and a fiber laser for obtaining high-output light of a single wavelength. The optical multiplexer according to the present invention is provided with input unitsanda wavelength multiplexing unita multiplexed light converting unitand an output unitLights of a plurality of wavelengths λand λare input to the input unitsandrespectively. The wavelength multiplexing unitwavelength-multiplexes the lights of the plurality of wavelengths λand λinput from the input unitsanddifferent for each wavelength to one multiplexed light. By wavelength-multiplexing, it is possible to multiplex without a loss. The multiplexed light converting unitgenerates Raman light with at least one wavelength out of the wavelengths λand λincluded in the multiplexed light from the wavelength multiplexing unitand converts the multiplexed light of the wavelengths λand λfrom the wavelength multiplexing unitto light of a single wavelength λincluded in a wavelength band of the Raman light.
