摘要

本文提出了一种理论,用于研究在具有缓冲气体的光密集介质中,在脉冲抽运下,热原子中的相干居群俘获(CPT)效应。考虑了激发态能级不简并的情况。基于对拉姆齐共振形状的分析,我们发现随着介质光密度的增加,CPT共振的光移的依赖性变得越来越重要。构造了CPT共振的光移与激发能级的超精细分裂大小、活性原子的浓度、温度和暗暂停时间的依赖关系。

Line shape and light shift of coherent population trapping resonance under Ramsey interrogation in ‘hot’ atoms in an optically dense medium
A theory is developed for the effect of coherent population trapping (CPT) in ‘hot’ atoms under pulsed pumping in an optically dense medium with a buffer gas. The case is considered when the excited level is not degenerate. Based on an analysis of the shape of Ramsey resonances, we show that with increasing optical density of the medium, the dependence of the light shifts of the CPT resonance becomes more and more nontrivial. The dependence of the light shifts of the CPT resonance on the magnitude of the hyperfine splitting of the excited level, concentration of active atoms, temperature, and duration of the dark pause is constructed.
