Special features of light-induced scattering of radiation (λ = 0.44 μm) with extraordinary polarisation in the SBN-75 photorefractive crystal are studied in detail and an efficient technique is proposed for exciting surface waves in this crystal. I

The potential of the dynamic holography method for testing the phase optical homogeneity of media transparent in visible light has been considered. This method is based on imaging samples in the scheme of two-wave mixing of the second-harmonic radiat

Excitation of nonlinear surface waves is studied at the SBN-75 crystal — air interface. The SBN-75 crystal is characterised by the diffusion-type photorefractive nonlinearity, the surface wave being excited in the surface layer and the depth of its

The Stepanov technique has been developed for SBN solid-solution crystal growth. We carried out a comparison of the growth conditions of SBN crystals in the traditional Czochralski method and new growing technique. The advantages of the Stepanov tech

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

Two-wave mixing allows one to change effectively Intensities, phases, space profiles, polarizations and time evolution of interacting beams [1,21. We will show, that two-wave mixing of partially coherent beams may be used to increase degree of cohere

Holographic grating in a photorefractive crystal may be recorded due to the diffusion of electrons or their drift in external or intrinsic photovoltaic dc field as a result of illumination by a static interference pattern. Those traditional mechanism

We demonstrate that two-wave mixing of partially coherent light beams inside a medium with an inertial nonlinear response allows one to increase the coherence substantially. An increase of the coherence function from 0.24 to 0.94 is demonstrated expe
