Four-wave mixing with optical pulses is considered analytically. It is shown that, whereas true time reversal of an amplitude pulse is not possible with continuous-wave pumping, this can be achieved by short-pulse pumping of a long, narrow, nonlinear medium, although time-dependent phase variations are not time reversed.
