| 摘 要： | 研究了级联四能级系统中双光子共振非简并四波混频(NFWM)由于加入耦合光场而产生的量子干涉效应，发现在强耦合场作用下NFWM频谱呈现AT劈裂，它反映的是两个缀饰态的能级.量子干涉还使NFWM信号被抑制或增强.此方法牵涉到三光子共振，因此可以成为研究原子或分子高激发态的有效光谱学工具.

| Abstract: | We study the quantum interference in two-photon resonant nondegenerate four-wave mixing (NFWM) in a dressed cascade four-level system in which the two upper levels are coupled by a strong laser field. We find that in the presence of a strong coupling field, two-photon resonant NFWM spectrum exhibits Autler-Townes splitting, which reflects the levels of the dressed states. It also leads to either suppression or enhancement of the NFWM signal. This scheme involves the resonant three-photon excitation, therefore, provides a new spectroscopic tool for studying highly excited atomic states with high sensitivity. |
