TLDR
In this article, the authors experimentally demonstrate cavity field control by another laser beam with three-level Lambda-type atoms inside an optical ring cavity, by adjusting the frequency detuning of the controlling beam (coupled to one of the atomic transitions).Abstract:
We experimentally demonstrate cavity field control by another laser beam with three-level \ensuremath{\Lambda}-type atoms inside an optical ring cavity. By adjusting the frequency detuning of the controlling beam (coupled to one of the atomic transitions), the intensity of the cavity field interacting with another atomic transition is switched on and off. Such all-optical switching between two steady states is caused by the enhanced Kerr nonlinearity due to atomic coherence in such system.read more

Applications of optical cavities in modern atomic, molecular, and optical physics
Jun Ye,T. W. Lynn +1 more
TL;DR: In this paper, the authors discuss applications of optical cavities in modern atomic, molecular, and optical physics, and explore exploration of quantum dynamics associated with the enhanced interaction between atoms and cavity field; where the structure of the cavity enables a large field amplitude associated with single intracavity photons.
