Investigation of efficiency of generation of difference-frequency laser radiation in waveguide
Abstract
Millimeter wavelength difference-frequency lasing was obtained by mixing the frequencies produced by two temperature-detuned ruby lasers in a LiNbO3 crystal in a rectangular waveguide. The conversion efficiency is studied as a function of the angle of incidence of the exciting beams on the crystal, as well as the angle between the exciting beams and their spatial overlap, at wavelengths of 4 and 8 mm. The experimental findings are in good agreement with the analytical figures. The results can be used in developing lasers, determining the spatial parameters of lasers, etc.
