Abstract
Single Cesium atoms are cooled and trapped inside a small optical cavity by way of a novel far-off-resonance dipole-force trap (FORT), with observed lifetimes of 2 - 3 seconds. The trapping field is provided by a TEM-00 mode of the cavity at a wavelength of 935.6 nm, and is such that the external potential for the center-of-mass motion is only weakly dependent on the atom's internal state. Continuous real time observations of single trapped atoms in a regime of strong coupling are reported, with mean duration 0.4 s and with individual events lasting ~ 1 s.
