摘要：<p>[Object] A fiber laser device capable of shortening the rise time of output laser light and suppressing laser light output except for an output period is provided. [Means to attain the object] A fiber laser device 100 includes: a seed laser light source 10, a pumping light source 20, an amplification optical fiber 30, a wavelength converter 71, a wavelength selecting filter 73, an output section 50, and a controller 60. The controller 60 controls the seed laser light source 10 and the pumping light source 20 to change from a preliminary pumping state to an output state. In the preliminary pumping state, the laser light is not output from the seed laser light source 10, the pumping light is output from the pumping light source 10, and the pumping light has such an intensity that the wavelength of the laser light emitted and output from the amplification optical fiber 30 is not converted by the wavelength converter 71. In the output state, the laser light is output from the seed laser light source 10, the pumping light is output from the pumping light source 20, 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 fiber 30 is converted by the wavelength converter 71.</p>
