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.

本文从两个方面对原子-腔进行了研究 排气中 其中一个研究领域将是共振荧光 耦合到简并光学谐振腔模式的单个原子。 这样的系统表现出两个共振峰，一个靠近自由- 空间原子共振频率和第二附近的空- 谐振腔频率 这些峰值演变成正常模式 当腔频率和原子频率 一致。 对这种行为的详细研究， 共振，将提供微观动力学量子信息 流程. 受激发射和吸收的影响将 也被研究。 第二个研究领域将是 一种原子-腔系统，其中原子（或多个原子）是在 一种颠倒的状态 这种系统的增益可以很大， 发射率和线宽将进行研究，以观察 从增强自发辐射到受激辐射的跃迁 发射（“原子腔激光器”）。 光子统计也将是 研究了
