Abstract: A wavelength conversion element is provided with a substrate including a nonlinear optical single crystal having a periodically poled structure, wherein a visible light transmittance of the substrate is 85% or higher when ultraviolet light is irradiated to the substrate. Further, a laser light having an average output of 1 W or more is outputted by shortening a wavelength of inputted laser light having a wavelength of 640 nm to 2000 nm. By improving visible light transmission characteristics when the ultraviolet light is irradiated in this way, a breakdown of crystal can be prevented and a stabilization of output characteristics at high output can be realized. As a result, an absorption of green light induced by ultraviolet light can also be suppressed and a saturation of output and the breakdown of crystal can be avoided.

Abstract: There is a problem that in the connection portion between a rare-earth-doped double clad fiber and a single mode fiber, pumping light leaks in a portion having the coating, and the fiber generates heat partially with this energy and deteriorates. Also, there is another problem that the output is limited as the oscillation wavelength becomes shorter. Accordingly, in a laser light source device formed by combining a fiber laser and a fiber amplifier, by using the residual pumping light in the fiber laser as the pumping light in the fiber amplifier, it is possible to enhance the reliability by preventing the fiber deterioration caused by the residual pumping light. Further, by amplifying the output in the fiber amplifier in the latter stage without any limitation on the pumping light output, it is possible to increase an output of the oscillation light.
