D. A. B. Miller, "Time Reversal of
Optical Pulses by Four-Wave Mixing," Optics Lett. 5, 300-302 (1980) 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.
