室温腔中三能级原子气体的集体激发

Collective excitations using a room-temperature gas of 3-level atoms in a cavity

G. T. Hickman

摘要:

本文从理论上研究了双模光腔中室温三能级原子系综,着重研究了光场反向传播的情况。我们发现,在大失谐的限制问题承认相对简单和直观的解决方案。当一个经典场驱动其中一个跃迁时,系统等价于一个多普勒展宽被抑制的二能级原子系综。相比之下,当同一个跃迁由单个光子驱动时,系统的行为就像一个两能级原子。后一个结果在量子非线性光学的背景下特别相关。

英文摘要:

We theoretically investigate an ensemble of three-level room-temperature atoms in a two-mode optical cavity, focusing on the case of counterpropagating light fields. We find that in the limit of large detunings the problem admits relatively simple and intuitive solutions. When a classical field drives one of the transitions, the system becomes equivalent to an ensemble of two-level atoms with suppressed Doppler broadening. In contrast, when the same transition is driven with a single photon, the system collectively behaves like a single two-level atom. This latter result is particularly relevant in the context of quantum nonlinear optics.
