摘要

研究了耦合光共振时Rb87冷原子D1线形能级体系中电磁感应透明吸收曲线的不对称现象.发现间隔为814 MHz的另一个激发态能级导致了不对称现象.不对称现象的根本原因是受激拉曼散射, 同时发现透明窗口两侧不对称的吸收峰的幅值比与耦合光强成正比.理论拟合与实验数据符合得较好.

关键词:

The asymmetry of the absorption curve of electromagnetically induced transparency by a resonant coupling field in -type three-level systems for Rb87 cold atoms is investigated. We find that it is the other excited state, separated by an interval of 814 MHz, that induces this phenomenon. The primary cause of it is the stimulated Raman scattering. We also find that the ratio between the heights of the absorption peaks on the two sides of the transparency window is proportional to the intensity of the coupling beam. The theoretical result agrees well with the experimental data.

Keywords:
