在最近的一篇论文中[Y]。Xiao et al.，物理学。我们将扩散诱导的拉姆齐窄化描述为一种普遍现象，在这种现象中，相干性在相互作用区域（如激光束）内外的扩散会导致相关共振线形的光谱窄化。本文详细介绍了扩散诱导Ramsey变窄的重复相互作用模型，重点介绍了其在缓冲气池中原子蒸汽电磁感应透明（EIT）中的应用。我们将该模型与实验数据和数值计算进行了比较。
In a recent paper [Y. Xiao et al., Phys. Rev. Lett. 96, 043601 (2006)] we characterized diffusion-induced Ramsey narrowing as a general phenomenon, in which diffusion of coherence in-and-out of an interaction region such as a laser beam induces spectral narrowing of the associated resonance lineshape. Here we provide a detailed presentation of the repeated interaction model of diffusion-induced Ramsey narrowing, with particular focus on its application to Electromagnetically Induced Transparency (EIT) of atomic vapor in a buffer gas cell. We compare this model both to experimental data and numerical calculations.
