A solid state laser which has Y.sub.x Gd.sub.1-x VO.sub.4 doped with Nd wherein 0.ltoreq..times..ltoreq.0.5 as a solid laser medium.

Solid state laser

An optical wavelength conversion device is composed of an organic nonlinear optical material, and a cladding layer having a refractive index lower than the refractive index of the organic nonlinear optical material and covering the organic nonlinear optical material, thereby to convert a fundamental wave entering the optical wavelength conversion device to a second harmonic, and to radiate the second harmonic. At least one of device edge faces including edge faces of the organic nonlinear optical material is provided with a shielding layer for shielding the device edge face from ambient atmosphere, thereby to prevent the organic nonlinear optical material from sublimation and deterioration.
