Abstract

A novel setup for investigations in cavity quantum electrodynamics is described, which combines an optical microcavity (finesse 4.3 × 105) with an atomic 85Rb fountain, allowing full control over density and velocity of atoms entering the optical cavity. To demonstrate this point we study the temporal width of the transmission drops if slow single atoms pass through the cavity. We observe absorptive and dispersive single atom signals in the cavity transmission in real time.
