Abstract
We show that the relative phase of the grating components has a large effect on the temporal behavior of four-wave mixing. When the two main components of the grating are in phase, the temporal behavior, especially during grating erasure, is totally different from that when the two components are out of phase. We give experimental results of orthogonally polarized four-wave mixing for two different BaTiO3 crystals that are in good agreement with our theoretical calculations. In our calculations we use a simplified numerical method to solve the coupled-wave equations, and the temporal analysis is based on a model with multiple charge recombination.
