摘要： Upon obtaining green light as wavelength converted light by causing infrared light to be incident on a wavelength conversion element, the absorption of the green light occurs due to the generation of ultraviolet light as sum-frequency light of the infrared light and the green light in the wavelength conversion element and the destruction of a crystal composing the wavelength conversion element occurs due to heat generated at this time. In a laser wavelength converter of the present invention, a condensed position of the infrared light in the wavelength conversion element is deviated from a position assumed to be optimal when the influence of the generated heat is ignored. Consequently, crystal destruction is suppressed, a high-efficiency wavelength conversion is enabled and high-output wavelength converted light exceeding several watts, which was difficult to attain in conventional wavelength conversion elements, is attained.

摘要： 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.
