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

从原子腔发射的两个方面进行了研究。一个研究领域将是一个单原子的共振荧光耦合到一个简并的光学谐振器模式。这种系统有两个共振峰，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。当腔频率与原子频率重合时，这些峰演化为正模分裂。对这种行为的详细研究，包括开启和关闭共振，将提供微动力学量子过程的信息。受激辐射和受激吸收的影响也将被研究。第二个研究领域将是原子空腔系统的发射，其中原子（或原子）是在倒置状态下制备的。这种系统的增益可能很大，并且将研究发射速率和线宽，以观察从增强自发发射到受激发射（“原子腔激光”）的转变。光子统计也将被研究。

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.
