A review is given of theoretical and experimental investigations of the role of the fanning in the operation of self-pumped four-wave mixing systems. It is shown that in some cases the fanning determines the dynamics of such systems and their final s

Most photorefractive crystals suitable for four-wave systems of phase self-conjugation and mutual conjugation have a fairly high level of light-induced scattering (fanning). This may imply that the nonlinearity of a crystal is too strong for optimal

A two-dimensional theory of the interaction of two optical beams in a photorefractive medium is formulated. Beams having planar and parabolic intensity distributions are used to analyze the laws governing energy exchange and distortion of the beam pr

An investigation is reported of the stability of stationary nonlinear states of the fields of optical waves in a system comprising two coupled regions of a degenerate four-wave interaction pumped by two mutually incoherent optical beams. The importan

An analysis is made of stimulated scattering in a ring resonator formed by a self-intersecting beam with simultaneous rotation and contraction of the beam due to feedback. Conditions for the excitation of lasing are obtained and the phase conjugation

The results indicated that the dynamics and steady states of a semilinear phase-conjugating mirror based on a photorefractive crystal are governed by small "seeds" of scattered waves at the entry to a nonlinear medium. The relationships for the deter

The steady-state transverse structure of light beams is determined for a parametric ring oscillator which is formed as a result of self-intersection of a signal light beam in a nonlinear medium. The example of a signal beam with a Gaussian intensity
