Dynamics of a coherently driven atom in a high-finesse optical resonator — •Martin Eckstein, Wolfgang Alt, Stefan Brakhane, Tobias Kampschulte, Sebastian Reick, René Reimann, Artur Widera, and Dieter Meschede — Institut für Angewandte Physik, Universität Bonn

In our experiment we transport a single cold caesium atom into a high-finesse optical resonator using an optical dipole trap [1]. By monitoring the transmission of a probe laser beam resonant with the cavity we measure the atomic spin state [2]. We study the dynamics of a coherently driven two-level atom inside our cavity. The driving source consists of two phase locked diode lasers that connect the atomic states by a two-photon Raman process. We study the influence of the non-destructive measurement on the evolution of the system.
