Abstract
A wavelength conversion laser light sourcehas: a laser light source configured to generate fundamental wave laser light; and a wavelength conversion elementprovided with a periodic polarization reversal structure configured to convert the fundamental wave laser light which is incident onto the periodic polarization reversal structure into different laser light in wavelength wherein the wavelength conversion element includes different polarization reversal regions in period; and a polarization reversal axisof at least one of the polarization reversal regions is inclined with respect to an incident optical path of the fundamental wave laser light on the wavelength conversion element.
