Coherence time of a cold-atom laser below threshold
Graeme Harvie, Adam Butcher, Jon Goldwin
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…
In-situ Raman gain between hyperfine ground states in a potassium magneto-optical trap
Graeme Harvie, Adam Butcher, Jon Goldwin
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…
Directional bistability and nonreciprocal lasing with cold atoms in a ring cavity
Balazs Megyeri, Graeme Harvie, Andreas Lampis +1
We demonstrate lasing into counter-propagating 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 t…
Why material slow light does not improve cavity-enhanced atom detection
B. Megyeri, A. Lampis, G. Harvie +2
We discuss the prospects for enhancing absorption and scattering of light from a weakly coupled atom in a high-finesse optical cavity by adding a medium with large, positive group…
