LOCALIZATION IN SEMICLASSICAL LASER COOLING

Extending the work of a previous paper, we calculated the friction and diffusion coefficients in three-dimensional optical molasses for diff erent laser configurations and for different atomic transitions in a s emiclassical approach. We introduce and calculate a potential, and we present averages and temperatures obtained using this potential in a l ocalization model. Compared with the usual calculations, this model re presents an improvement for all cases we have been able to compare wit h exact calculations or with experimental results.
