Abstract
The process of second harmonic generation (S.H.G.) in collimated light beams with Gaussian distribution of light intensity at the interaction of typeo+e→e in a uniaxial negative crystal for a case of perpendicular incidence on the boundary plane is studied in this paper. In case of very wide light beams of fundamental frequency with Gaussian distribution of light intensity, the coefficient of mutual energy conversion in the region of small energy conversions is about one half of that following from the model of the interaction of unlimited plane waves. The process of S.H.G. at the interaction o+ e→e is less profitable than that of interaction o+o→e especially for narrow fundamental-frequency light beams as a consequence of the anisotropic mutual divergence of both beams.
