Abstract
A few years ago in photoretractive crystals of LiTaO3:Gu [1] and LlNbO3:Cu [2] a new nonlinear optic phenomenon, called the parametric scattering of “holographic type”, has been observed. As in the case of well-known [3] wide-angel spicies of photoinduced scattering, this process was degenerate. But it occured under condition of phase-matching for four coupling waves: and hence had narrow spatial spectrum, where KL, KS1, KS2 are the wave vectors of the pump and two phase-conjugated scattered waves on fequency ω.
