Abstract
The invention relates to a fiber laser device. In the preliminary pumping state, the laser light is not output from the seed laser light source, the pumping light is output from the pumping light source, and the pumping light has such an intensity that the wavelength of the laser light emitted and output from the amplification optical fiberis not converted by the wavelength converter. In the output state, the laser light is output from the seed laser light source, the pumping light is output from the pumping light source, and the laser light and the pumping light have such intensities that the wavelength of the laser light amplified and output by the amplification optical fiberis converted by the wavelength converter
