Abstract
The dynamic process of two-wave mixing in LiNbO3:Fe crystals was calculated numerically by use of the basic differential equations governing the time- varied two-wave coupling, and the phase change, the space-charge electric f ield and the gratings in the crystals, and other physical parameters were a nalyzed. The photorefractive self-enhancement effect in the crystals was ex plained and an effective way to improve the diffraction efficiency of photo refractive gratings was suggested.
