znp2单晶中激子的自由感应衰减信号表现出意想不到的时间演化、极化子拍和相干倾角。我们证明了这种现象来自于样品的非零厚度和激发脉冲的非零时间宽度。系统的数值计算与数据有很好的定性一致性。这些结果对于理解激子与光场之间相干相互作用的实验结果是非常重要的
The free induction decay signal from excitons in a ZnP 2 single crystal shows an unexpected temporal evolution, polariton beat, and coherent dip. We show that the erects come from a nonzero thickness of the sample and nonzero time width of the excitation pulses. A systematic numerical calculation provides good qualitative agreement with the data. These erects are very important in understanding the experimental results which deal with the coherent interaction between excitons and optical fields
