Cooling cesium atoms in a Talbot lattice
Laboratoire Kastler Brossel, Ecole Normale Supérieure, 24 rue Lhomond, 75231 Paris Cedex 05, France
Accepted: 2 October 1998
Three-dimensional cooling of cesium atoms is observed in the lin lin configuration when one beam is transmitted through a periodic phase grating. Localization in Talbot planes is observed with a CCD camera. An unusual dependence of the temperature on the optical pumping rate is found and explained with a simple physical model. The results are confirmed by semiclassical Monte Carlo simulations.
