Damping rates of the atomic velocity in Sisyphus cooling

Laurent Sanchez-Palencia, Michele Schiavoni, F.-R. Carminati +2 more

We present a theoretical and experimental study of the damping process of the atomic velocity in Sisyphus cooling. The relaxation rates of the atomic kinetic temperature are determined for a three-dimensional lin⊥lin optical lattice. We find that the damping rates of the atomic temperature depend linearly on the optical pumping rate, for a given depth of the potential wells. This is at variance with the behavior of the friction coefficient as calculated from the spatial diffusion coefficients within a model of Brownian motion. The origin of this different behavior is identified by distinguishing the role of the trapped and traveling atoms.We present a theoretical and experimental study of the damping process of the atomic velocity in Sisyphus cooling.

Cooling and trapping cesium atoms in pi-polarized potential wells: the jumping regime of optical lattices

C. Mennerat-Robilliard, Luca Guidoni, J.-Y. Courtois +1 more

We present an experimental investigation of a three-dimensional (3D) optical lattice where the light polarization is linear at the bottom of the potential wells instead of being circular as in previous studies. In the present situation, optical pumping induces frequent transitions between differently light-shifted Zeeman sublevels (jumping regime). However, narrow vibrational lines are still observed as a result from a motional narrowing-like phenomenon taking place in this lattice. The atomic kinetic temperature is investigated and shown to be lower than in a standard 3D lin ⊥ lin optical lattice.We present an experimental investigation of a three-dimensional (3D) optical lattice where the light polarization is linear at the bottom of the potential wells instead of being circular as in previous studies.
