摘要

光与物质的相互作用可以产生许多奇特的量子光学现象, 电磁诱导透明和电磁诱导吸收是其中最典型的现象.本文在通常的Λ型三能级系统中引入射频场作用于激发态的精细结构能级之间，组成光学-射频双驱动场共同激发原子的相干跃迁，使系统的吸收特性出现电磁诱导透明和电磁诱导吸收两种量子相干效应.通过讨论双驱动场开启后直到系统达到稳定的量子相干过程，分析电磁诱导透明和电磁诱导吸收随时间的产生和转化，得到两种量子相干现象之间的关联性及对其进行量子调控的方法.

Abstract

The interaction of light and matter can induce many strange quantum optical phenomena, in which EIT and EIA are the most typical ones. In this paper, a radio-frequency field is introduced between two hyperfine levels of the excited state into a well-studied lambda three level system to form a modified quasi-lambda four level system consisting of an optical-radio two-photon coupling field and a probing field. Both EIT and EIA can be obtained in this system. By discussing the quantum coherence process after the optical-radio field is turned on until the system is stable, the generation and transformation of EIT and EIA during this period of time are analyzed, which is helpful to probe the correlation between two phenomena and to seek the method to regulate and control them.
