  • Abstract
    During the erasure of a photorefractive grating in Bi12SiO20, the space-charge field moves at a constant velocity and its amplitude exponentially decays. The experiment confirms that the diffracted beam is frequency-shifted and the amount of frequency shift is equal to that required for optimum beam coupling in nearly degenerate two-wave mixing.
