摘要: Recording of a π/2-shifted photorefractive grating in iron-doped BaTiO3 by orthogonally polarized waves is reported. The unidirectional intensity transfer from ordinary to extraordinary attributed the photovoltaic process charge redistribution. sign antisymmetric component tensor found, and an estimate its absolute value given.
