The first observation of an anisotropically recorded grating (with two orthogonally polarized
beams) in photorefractive KNbO 3: Fe is reported. We attribute the effect to influences of the …

A nonlinear theory is presented for the formation of hexagonal optical structures in a
photorefractive medium equipped with a feedback mirror. Oppositely directed beams in …

Asymmetric light transmission of up to 113 and 59% for two antiparallel beam directions has
been measured in photorefractive KNbO_3: Mn. The wavelength dependence of the …

Holographic scattering processes in photorefractive KTa1− xNbxO3 (KTN) crystals are
investigated resulting from the simultaneous action of one or two pump beams. Different …
