对可饱和染料简并四波混频产生的瞬态相位共轭进行了理论和实验研究。研究了两种特殊情况：（1）两个泵浦波和一个探测波同时开启的情况和（2）泵浦波在探测波入射之前就开启的情况。对于情况（1），对于高泵浦强度，在瞬态反射率中出现峰值，而对于情况（2），反射率随时间单调增加直到稳态值，而与泵浦强度的值无关。
Transient phase conjugation by degenerate four-wave mixing in saturable dyes is investigated theoretically and experimentally. Two special cases are examined: (1) the case in which two pump waves and a probe wave are simultaneously turned on and (2) the case in which the pump waves are turned on well before the incidence of the probe wave. For case (1) a peak appears in the transient reflectivity for high pump intensity, while for case (2) the reflectivity increases monotonically with time up to the steady-state value irrespective of the value of the pump intensity.
