Abstract

The formation dynamics of crossed-beam photorefractive gratings formed by the in Fe doped LiNbO₃ crystal is studied based on jointly solving the material equations and the two-dimensional coupled-wave theory. The numerical calculations of the temporal and the spatial evolutions of the space-charge field and the light modulation depth are given, and the influence of the recording conditions, including the recording wavelength, the two-dimensional sizes of the holographic grating are presented, and the time evolution of diffraction efficiency during holographic recording is also presented.
