【Abstract】 The coupled wave equation for light diffraction from volume hologram grating in photorefractive crystals are derived by carefully considered the anisotropio nature of crystals. The solutions of these equations are also obtained. With the formulas in this paper, the results of experiment in which the two incident beams are asymmetrical can be explained.更多还原
