Nonlinear coupling between two Zeeman coherence gratings stored in cold atoms

Rafael Alves De Oliveira, D. Felinto, J. W. R. Tabosa

We investigate the storage and the nonlinear coupling of two Zeeman coherence gratings in an ensemble of cold cesium atoms. This nonlinear coupling was revealed through the analysis of the total energy that can be extracted from the atomic medium as a function of the relative intensities of the grating writing beams, which presented a minimum when their intensities were made equal. A theoretical model using the density matrix formalism accounts quantitatively well for the observed results and allowed us to identify several channels in which energy can be delivered in the reading process.We investigate the storage and the nonlinear coupling of two Zeeman coherence gratings in an ensemble of cold cesium atoms.

Generation of Correlated Light Pulses from a Coherently Prepared Atomic Ensemble

D. Moretti, D. Felinto, J. W. R. Tabosa

We investigate the generation of correlated light beams in a coherently prepared atomic system consisting of cold cesium atoms. Double Bragg diffraction into a Zeeman coherence grating is employed to conditionally extract the stored information.
