Propagation effects of pulsed Rydberg excitations in thermal vapor — •Fabian Ripka, Robert Löw, and Tilman Pfau — 5. Physikalisches Institut, Universität Stuttgart

We present numerical simulations of three-level Maxwell-Bloch equations and examine propagation effects of a pulsed two-photon Rydberg excitation in thermal atoms. This work is related to the recent observation of Rabi oscillations to Rydberg states in thermal vapor [1]. While the latter could be reproduced neglecting spatial dependency, we show that for high optical densities and/or low Rabi frequencies effects of light propagation have to be taken into account. Finally we compare our simulations to corresponding experimental results.
