This project is a study of the dynamics and spectra of optically driven atoms in the case that they are exposed to a perturbed electromagnetic mode density. It involves the design and construction of cavities whose perturbation of the electromagnetic mode density is particularly strong. Optical trapping techniques will be employed to eliminate transit-time limitations on the size of optical cavities or their active regions. Owing to the fundamental changes in driven atom dynamics that can occur in the presence of a perturbed electromagnetic mode density, the present studies may lead to the operation of optical devices in hitherto unaccessible regimes. A secondary objective of this work will be to investigate the response of free-space atoms to complex, for example bichromatic, excitation fields.

这个项目是研究光驱动原子在微扰电磁模式密度下的动力学和光谱。它涉及到电磁模式密度扰动特别强的腔体的设计和构造。光学捕获技术将被用来消除对光学腔或其有源区大小的渡越时间限制。由于在微扰电磁模式密度存在的情况下，驱动原子动力学可能发生根本变化，因此本研究可能导致光学器件在迄今无法进入的区域中运行。这项工作的第二个目标将是研究自由空间原子对复杂的，例如双色激发场的响应。
