在Pr:YSO晶体中,理论计算表明利用部分受激拉曼绝热过程可以在晶体的精细能级之间制备最大原子相干。一个探测脉冲与制备好的原子相干系统作用,可以得到增强的拉曼散射信号。还讨论了一些因素对拉曼信号强度的影响,为相关的实验研究提供了理论依据。

The result of theoretical calculation shows that fractional stimulated Raman adiabatic passage can create maximal coherence between the hyperfine levels in a Pr:YSO crystal. A probe pulse interaction with the atomic coherent system leads to efficient generation of a Raman signal field. The influence of some factors on the signal is discussed also,these theoretical results provide useful reference for the related experimental investigation.
