Coherent excitation of Rydberg atoms in an ultracold gas. Deiglmayr, J., Reetz-Lamour, M., Amthor, T., Westermann, S., de Oliveira, A. L., & Weidemueller, M. Optics Communications, 264(2):293–298, August, 2006. doi abstract bibtex We demonstrate two schemes for the coherent excitation of Rydberg atoms in an ultracold gas of rubidium atoms employing the three-level ladder system 5S(1/2)-5P(3/2)-nl(j). In the first approach rapid adiabatic passage with pulsed laser fields yields Rydberg excitation probabilities of 90% in the center of the laser focus. In a second experiment two-photon Rydberg excitation with continuous-wave fields is applied which results in Rabi oscillations between the ground and Rydberg state. The experiments represent a prerequisite for the control of interactions in ultracold Rydberg gases and the application of ultracold Rydberg gases for quantum information processing.
