Dynamic holograms formed in LiNbO3 crystals by the transverse photogalvanic effect

Dynamic holograms were formed in Z-cut LiNbO₃:Fe crystals. Two beams with the "ordinary" polarization and mutually orthogonal electric field vectors were used for the first time to record a grating. The conditions for the occurrence of the normal and anisotropic diffraction were determined. An estimate was obtained of the component β₂₂ of the photogalvanic effect tensor.
