Abstract
The light-induced scattering in photorefractive crystals has been investigated widely by many researchers because it has important effects on photorefractive holograms, phase conjugation, etc. The characteristics of the pattern of the light-induced scattering depend on polarization and orientation of the illumination beam relative to the crystallographic axes of the crystal. Most studies of the light-induced scattering to date were performed with LiNbO3:Fe, LiTaO3, and BaTiO3 crystals at fixed distances between focusing lenses and samples.[1,2,3] KNbO3 is an important crystal used in two-wave mixing, phase conjugation, and dynamic holography. This paper presents the features of light-induced scattering and "position dispersion" of KNbO3:Fe crystal. The anisotropic scattering from the KNbO3:Fe crystal is shown to be dominated by light-induced lensing.
