ABSTRACT:
A resonator, including a radiation generator, mirrors located at either side of the radiation generator in the path of radiation emitted from the generator, and a coupling means are arranged to couple primary radiation of predetermined frequency into the resonator and extract secondary radiation therefrom at a frequency which is shifted with respect to the frequency of the primary radiation, the frequency shift arising due to parametric interaction of the primary radiation. In accordance with the invention, the coupling means includes dichroic mirrors located in the path of radiation of the optical resonator at an inclination with respect to the path and having the characteristic of being highly reflective for radiation of the wavelength of the primary radiation and highly transmissive to radiation of a wavelength of the secondary radiation.
