摘要：

Sideband laser cooling using stimulated Raman transitions is performed on trapped cesium atoms. The confinement is produced by a far-off-resonance dipole trap consisting of two crossed YAG beams which, by interference, create a one-dimensional optical lattice. In a pure intensity lattice, we measure a 1D temperature of T = 6 mu K corresponding to a mean quantum vibrational number of about [n(v)] = 0.75. In a polarization gradient lattice, the final temperature is T = 3.6 mu K corresponding to [n(v)] similar or equal to 2.4.
