Fundamental Studies of Visible Superfluorescence and Atom- Field Interactions in an Optical Resonator

对原子-腔体发射的两个方面进行了研究。其中一个研究领域将是耦合到简并光学谐振器模式的单个原子的共振荧光。这样的系统有两个共振峰，一个在自由空间原子共振频率附近，另一个在空腔频率附近。当腔场频率和原子频率重合时，这些峰值演化为正常模分裂。对这一行为的详细研究，包括开启和关闭共振，将提供关于微观动力学量子过程的信息。还将研究受激发射和吸收的影响。第二个研究领域将是原子-腔系统的发射，在该系统中，原子(或多个原子)是以倒置状态制备的。这种系统的增益可以很大，并将研究发射率和线宽，以观察从增强自发辐射到受激辐射(原子-腔激光)的转变。还将研究光子统计。

Investigations are carried out on two aspects of atom-cavity emission. One research area will be the resonance fluorescence of a single atom coupled to a degenerate optical resonator mode. Such a system exhibits two resonant peaks, one near the free- space atomic resonance frequency and a second near the empty- cavity frequency. These peaks evolve into the normal mode splitting when the cavity frequency and the atom frequency coincide. A detailed study of this behavior, both on and off resonance, will provide information on micro-dynamical quantum processes. Effects of stimulated emission and absorption will also be studied. A second area of study will be the emission of an atom-cavity system in which the atom (or atoms) is prepared in an inverted state. The gain for such a system can be large, and emission rates and linewidths will be studied to observe the transition from enhanced spontaneous emission to stimulated emission ("atom-cavity laser"). Photon statistics will also be studied.
