论文摘要
本教程介绍了热碱蒸气中电磁诱导透明度（EIT）的理论和实验基础。我们首先在简单的固定原子系统中引入了EIT的简短现象学描述，并在EIT条件下得出了用于光学传输和分散的分析表达式。然后，我们关注原子的热运动如何影响EIT系统的各种参数。具体而言，我们分析了限量 - 体积相互作用区域中光学转变，弹道与扩散原子运动的多普勒拓宽，以及碰撞人口减少和反谐波。最后，我们讨论对于优化EIT实验至关重要的常见权衡，并简要介绍了典型的EIT实验设置。我们简要概述了当前和潜在的EIT应用程序。
This tutorial introduces the theoretical and experimental basics of Electromagnetically Induced Transparency (EIT) in thermal alkali vapors. We first introduce a brief phenomenological description of EIT in simple three-level systems of stationary atoms and derive analytical expressions for optical transmission and dispersion under EIT conditions. Then we focus on how the thermal motion of atoms affects various parameters of the EIT system. Specifically, we analyze the Doppler broadening of optical transitions, ballistic versus diffusive atomic motion in a limited-volume interaction region, and collisional depopulation and decoherence. Finally, we discuss the common trade-offs important for optimizing an EIT experiment and give a brief "walk-through" of a typical EIT experimental setup. We conclude with a brief overview of current and potential EIT applications.
