在铷蒸气中通过简并四波混频产生了时间反演的光学波前。一个非常大的和共振增强的电子非线性，描述的绝热以下（AF）模型，负责混合。AF非线性极化率的强度依赖性被示出来解释在高泵浦强度下观察到的转换效率的降低。
Time‐reversed optical wave fronts were generated by degenerate four‐wave mixing in rubidium vapor. An extremely large and resonantly enhanced electronic nonlinearity, described by the adiabatic following (AF) model, was responsible for the mixing. The intensity dependence of the AF nonlinear susceptibility was shown to explain the observed reduction in conversion efficiency at high pumping intensities.
