Normal-mode splitting in the spectrum of cavity coupled atoms is normally observed in the strong coupling regime. Here the authors demonstrate the existence of avoided crossings in the spectrum of an overdamped system of cavity coupled 87Rb atoms tha

The QSNET consortium is building a UK network of next-generation atomic and molecular clocks that will achieve unprecedented sensitivity in testing variations of the fine structure constant, $\alpha$, and the electron-to-proton mass ratio, $\mu$. Thi

We present experiments on ensemble cavity quantum electrodynamics with cold potassium atoms in a high-finesse ring cavity. Potassium-39 atoms are cooled in a two-dimensional magneto-optical trap and transferred to a three-dimensional trap which inter

We experimentally study the coherence time of a below-threshold Raman laser in which the gain medium is a gas of magneto-optically trapped atoms. The second-order optical coherence exhibits photon bunching with a correlation time which is varied by t

We study optical gain in a gas of cold 39K atoms. The gain is observed during operation of a conventional magneto-optical trap without the need for additional fields. Measurements of transmission spectra from a weak probe show that the gain is due to

We demonstrate lasing into counterpropagating modes of a ring cavity using a gas of cold atoms as a gain medium. The laser operates under the usual conditions of magneto-optical trapping with no additional fields. We characterize the threshold behavi

Collective strong coupling of cold potassium atoms in a high-finesse ring cavity is demonstrated. The results imply a large effective optical susceptibility, which sets the foundation for studies of cavity quantum electrodynamics with large dispersio
