Abstract : In papers 1-4 the possibility of new light beam generation by interactions of light waves in photorefrective crystals is shown. New beams appear due to the subharmonic formation of the main holographic grating. The analysis of subharmonic generation was carried out for crystals with nonlocal response and circular photogalvanic mechanism of grating recording. The vector diagram illustrating the latter type of interaction is represented. Here, the generated beam has polarization orthogonal to polarization of exciting waves.
