Abstract
In a wavelength conversion laser, a laser crystal is pumped by light and the wavelength of a solid state laser beam emitted from the laser crystal is converted by a nonlinear optical crystal having a periodic domain reversal structure and disposed in a resonator. A +c-face and a -c-face of the nonlinear optical crystal are electrically connected to each other at least at portions of the faces close to the optical path of the solid state laser beam.
