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.
