ABSTRACT:
An apparatus for wavelength conversion of laser light which can prevent optical destruction of a wavelength conversion element and achieve a high wavelength conversion efficiency. The apparatus for wavelength conversion of laser light has an optical focusing system for focusing the input laser light on the wavelength conversion element in an optical cavity, which optical focusing system makes the cross-sectional shape of a light beam non-circular, for example, elliptical.
