ABSTRACT:
An optical wavelength converter system includes a light source for emitting a fundamental wave, a fiber or optical waveguide type optical wavelength converter device for converting the wavelength of the fundamental wave and emitting a wavelength-converted wave, and an optical system for introducing said fundamental wave into the optical wavelength converter device. The optical wavelength converter device includes an element made of an organic nonlinear optical material and covered with a cladding layer which has a smaller refractive index than the refractive index of said element. The optical wavelength converter device is housed in a closed container which is filled with an inert medium such as perfluorocarbon oil to keep the element out of contact with an atmosphere such as air.
