Abstract:

A few years ago in photorefractive crystals of LiTaO3Cu 1 and LiNbO 3Cu 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-angle species of photoinduced scattering, this process was degenerate. But it occurred under condition of phase-matching for four coupling waves 2K sub LomegaK sub s1omega K sub s2omega and hence had narrow spatial spectrum, where K sub L, K sub s1, K sub s2 are the are the S2 wave vectors of the pump and two phase-conjugated scattered waves on frequency omega. The scattered radiation was polarized orthogonally in respect to the laser beam.
