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 [Formula presented]. Trapped atoms are observed continuously via transmission of a strongly coupled probe beam, with individual events lasting [Formula presented]. The loss of successive atoms from the trap [Formula presented] 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.
