Phys. Rev. Lett. 90, 133602 (2003) [4 pages]State-Insensitive Cooling and Trapping of Single Atoms in an Optical CavityReceived 4 November 2002; published 3 April 2003 Single cesium atoms are cooled and trapped inside a small optical cavity by way of a novel far-off-resonance dipole-force trap, with observed lifetimes of 2–3 s. Trapped atoms are observed continuously via transmission of a strongly coupled probe beam, with individual events lasting ≃1 s. The loss of successive atoms from the trap N≥3→2→1→0 is thereby monitored in real time. Trapping, cooling, and interactions with strong coupling are enabled by the trap potential, for which the center-of-mass motion is only weakly dependent on the atom’s internal state. © 2003 The American Physical Society URL:
