An optical wavelength converting device comprises an optical waveguide device. The optical waveguide device is provided with a waveguide, which is constituted of a solid laser medium doped with a rare earth metal and a nonlinear optical material for converting a wavelength. The solid laser medium and said nonlinear optical material are overlaid one upon the other. A cladding is formed of a material having a lower refractive index than the waveguide and accommodates the waveguide therein. Two edge faces of the optical waveguide device serve as a resonator for a laser beam, which has been produced by the solid laser medium.
