We have observed the phenomenon of stochastic resonance on the Brillouin propagation modes of a dissipative optical lattice. Such a mode has been excited by applying a moving potential modulation with phase velocity equal to the velocity of the mode.

We present a review of the work done with dissipative optical lattices so far. A dissipative optical lattice is achieved when a light field provides both velocity damping and spatial periodicity of the atomic density. We introduce the geometric prope

We present a detailed experimental study of a three-dimensional lin$\perp$lin bright optical lattice. Measurements of the atomic temperature and spatial diffusion coefficients are reported for different angles between the lattice beams, i.e. for diff

The dynamics of an atom localized in a periodic potential and submitted to a probe wave is studied theoretically and experimentally in a cesium optical lattice. Because the optical potential is not harmonic, two solutions for the amplitude of motion

Spatial diffusion of atoms in a disordered molasses created by a speckle field is studied both numerically and experimentally. It is shown that the ratio T/Ds (kinetic temperature divided by spatial diffusion coefficient) can be expressed as a simple

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 temperatur

All the bright optical lattices studied so far have been designed to obtain a circularly polarized light at the bottom of the optical potential wells. This condition minimizes the departure rate of the atoms from the fundamental adiabatic surface and

We present an experimental and theoretical study of the recoil-induced resonances in the transiers domain. We describe the time dependence of the atomic bunching in the optical potential. We show that the usual line shape which is proportional to the

We study the three dimensional cooling of cesium atoms using a four-beam optical lattice induced by a magnetic field. The lattice beams are tuned to the blue side of the Fg = 3 → Fe = 2 hyperfine component of the 6 S 1 2 → 6 P 3 2 transition. The
