| 摘 要： | 构建双耦合场作用下的N-型四能级系统，详细讨论系统的探测吸收特性随两个耦合场Rabi频率取不同值时的变化规律，得到EIT、Mollow和Autler-Townes双峰效应及其它们之间的相互转化规律。通过找出N-型四能级系统中的多个跃迁通道，将系统按跃迁通道拆分成多个子系统，不同的拆分方法实现了不同跃迁通道之间的量子干涉，从而使系统呈现出三种产生条件和物理本质不同的非线性效应。 |

| Abstract: | An N-type four level system where two coupling fields interact with two separate optical transitions was constructed in the present paper. By discussing the behaviors of probing field absorption profiles under the effect of different Rabi frequencies of two coupling fields, EIT, Mollow and Autler-Townes doublet can be seen and mutual transformation between them can be obtained. Multiple transition channels in the system were found and the results show that the system can be divided into several subsystems according to the transition channels. Quantum interference between different transition channels can be realized through different dividing methods, so three nonlinear effects with different generating conditions and physical nature can be seen in the system. |
