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.
摘要翻译：波长转换元件设置有包括具有周期性极化结构的非线性光学单晶的衬底，其中当将紫外光照射到衬底时，衬底的可见光透射率为85％以上。此外，通过缩短波长为640nm至2000nm的输入激光的波长，输出平均输出为1W以上的激光。通过以这种方式照射紫外线时的可见光透射特性的改善，可以防止晶体的破坏，并且能够实现高输出下的输出特性的稳定化。结果，也可以抑制紫外线诱发的绿光的吸收，可以避免输出的饱和和晶体的击穿。

摘要： An object of the invention is to increase the beam diameter of a laser beam, and perform high-output wavelength conversion without causing crystal damage. A laser wavelength conversion device includes a laser wavelength conversion element for allowing incidence of a laser beam as a fundamental wave to convert a part of the fundamental wave laser beam into a wavelength-converted laser beam having a wavelength different from a wavelength of the fundamental wave laser beam. The laser wavelength conversion element includes a non-linear optical crystal having periodically polarization reversed portions. The polarization reversed portions are formed in such a manner that a region where a wavelength conversion efficiency is substantially uniform extends in a polarization direction of the non-linear optical crystal. The incident laser beam is converted into the wavelength-converted laser beam with the wavelength conversion efficiency.
