Nonlinear Optics of Three-Level, Inhomogeneously-Broadened Atoms in an Optical Cavity

Julio R. Gea-Banacloche, Haibin Wu, Min Xiao

We study theoretically and experimentally the strongly-coupled, nonlinear regime of a hot vapor of three-level atoms in an optical cavity. Interesting effects include lasing without inversion and polariton peak splittings.

Observations cross-absorption modulation mediated by coherent population trapping in hot rubidium vapor

Michael Vern Pack, Ryan M. Camacho, John C. Howell

Using the four-level N-system discussed by Schmidt and Imamoglu, Opt. Lett. 21,1936(1996), we observe cross-absorption modulation in hot rubidium atoms. Quantum coherences from coherent population trapping create larger Kerr nonlinearities than conventional three-level cascade systems.

Transverse optical and atomic pattern formation

Bonnie L. Schmittberger, Daniel J. Gauthier

The study of transverse optical pattern formation has been studied extensively in nonlinear optics, with a recent experimental interest in studying the phenomenon using cold atoms, which can undergo real-space self-organization. Here, we describe our experimental observation of pattern formation in cold atoms, which occurs using less than 1 μW of applied power. We show that the optical patterns and the self-organized atomic structures undergo continuous symmetry breaking, which is characteristic of nonequilibrium phenomena in a multimode system. To theoretically describe pattern formation in cold atoms, we present a self-consistent model that allows for tight atomic bunching in the applied optical lattice. We derive the nonlinear refractive index of a gas of multilevel atoms in an optical lattice, and we derive the threshold conditions under which pattern formation occurs. We show that by using small detunings and sub-Doppler temperatures, one achieves intensity thresholds for pattern formation that are reduced by two orders of magnitude compared to warm atoms.The study of transverse optical pattern formation has been studied extensively in nonlinear optics, with a recent experimental interest in studying the phenomenon using cold atoms, which can undergo real-space self-organization.
