Abstract

An end surfaceof a solid-state laser elementis sloped in such a way that, assuming that laser light is incident upon air from the end surface, an angle of incidence which a normal to an inner side of the end surface forms with a traveling direction of the laser light substantially matches the Brewster angle at the incidence plane, an end surfaceof a wavelength conversion elementis sloped in such a way that, assuming that the laser light is incident upon air from the end surface, an angle of incidence which a normal to an inner side of the end surface forms with a traveling direction of the laser light substantially matches the Brewster angle at the incidence plane, and the end surfaceand the end surfaceare arranged in such a way as to be opposite to each other.
