Nonlinear theory of nondegenerate beam coupling through phase-locked detection in an ac field.
Different frequency beams interact through the static grating recorded by their running interference pattern in an external ac field. The influence of the self-diffraction through the regular degenerate and nondegenerate interaction is studied theoretically. The depletion of all the waves is taken into account.
