摘要: We have analytically solved the problem of N mutually incoherent pairs beams in photorefractive media, each pair which shares a common grating. The results are applied to study simultaneous read–write dynamic holograms with comparable intensity. diffraction efficiency is shown be nonlinear function read-beam intensity and nonreciprocal respect readout from two input ports. A complete energy transfer between write occurs finite thickness crystal, contrast infinite required standard two-beam coupling case.
