CAVITY-INDUCED INTERFERENCE PATTERN WITH DARK CENTER FROM 2 FLUORESCING ATOMS

We show that the resonance fluorescence from a symmetric system of two incoherently pumped atoms coupled to a cavity mode produces interfere nce fringes that possess a minimum on the symmetry plane. This unique deviation from Young-type interferences can be explained intuitively b y the process of stimulated emission and reabsorption, leading to a ca vity-induced anticorrelation of the atomic dipoles. Detailed considera tion of an optical pumping scheme reveals the surprising role of cavit y damping. We propose an experiment utilizing a two-level system in In +.
