论文摘要
我们提出了一个模型，用于计算通过使用Rydberg Atom电磁诱导的透明度来探测AC电场幅度时拓宽的Autler-Townes光谱。该模型将原子蒸气近似为多层培养基，并使用Beer的定律通过许多离散的薄段组合探针束吸收，从而复制了实验测量中看到的扩展。监测总光谱传输或相延迟时，该方法可以轻松地应用于其他非均匀光学参数。场不均匀存在于无与伦比的波导和玻璃蒸气细胞的站立波中，这通常是由于源特性和环境反射所致。我们介绍了由各种类型的电场分布引起的扩展和失真效应，并将该模型与从测得的原子光谱获得的结果进行比较。
We present a model for calculating broadened Autler-Townes spectra when probing ac electric field magnitudes by use of Rydberg atom electromagnetically-induced transparency. This model approximates the atom vapor as a multi-layered media and uses Beer's law to combine probe beam absorption through many discrete thin segments, replicating the broadening seen in experimental measurements. The methodology can be easily applied to other non-uniform optical parameters when monitoring total spectral transmission or phase delay. Field non-uniformity is present in standing waves of unmatched waveguides and glass vapor cells, which are generally due to source characteristics and environmental reflections. We present broadening and distortion effects caused by various types of electric-field distributions, and compare this model to results obtained from measured atomic spectra.
