Interleaved dual-species arrays of single atoms using a passive optical element and one trapping laser Open
We demonstrate trapping of individual rubidium (Rb) and cesium (Cs) atoms in an interleaved array of bright tweezers and dark bottle-beam traps, using a microfabricated optical element illuminated by a single-laser beam and a 4 f system wi…

<i>In situ</i> Raman gain between hyperfine ground states in a potassium magneto-optical trap Open
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 gai…

Directional Bistability and Nonreciprocal Lasing with Cold Atoms in a Ring Cavity Open
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 thres…

Material slow light does not improve cavity-enhanced metrologies Open
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 index of refraction. The slow-light effect is known to narr…

Observing coherence effects in an overdamped quantum system Open
It is usually considered that the spectrum of an optical cavity coupled to an atomic medium does not exhibit a normal-mode splitting unless the system satisfies the strong coupling condition, meaning the Rabi frequency of the coherent coup…

Collective strong coupling of cold potassium atoms in a ring cavity Open
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 …

Steep dispersion and coherent control of Faraday rotation in a potassium vapor cell Open
Electromagnetically induced transparency (EIT) was studied in a heated vapor cell of potassium without buffer gas or anti-relaxation coating. Transparency windows 60 times narrower than the natural line width and group indices exceeding 60…
