Different types of selfdiffraction (isotropic and anisotropic) are described theoretically. It is shown that anisotropic selfdiffraction differs substantially from the isotropic one: for instance in nonpolar crystals the direction of the energy exchange between two beams depends on the wave polarisation. Several new types of two-wave and four-wave schemes of phase conjugation are discussed. [Russian Text Ignored].
