title: Properties of transient degenerate four-wave mixing involving the relaxation effect: an investigation.
abstract: A series of phenomenological relaxation equations have been introduced to describe the formation and decay of a grating. The influences of medium relaxation on the transient properties of degenerate four-wave mixing were studied theoretically and experimentally. As we studied the backward wave shape, the accumulation and smoothing effects were observed. The theory agreed well with the experimental results.
