Abstract
We study the properties of a magneto-optical trap of Rubidium in the
limit of very large number of atoms (up to N
). In
this regime we observe a new scaling law for the size of the MOT (
1/2). Several physical ingredients could
possibly contribute to this new behavior : a correction of the
spring constant due to the shadow effect, multiple scattering beyond
double scattering and non linear spatial dependence of the forces.
This study should allow to design new compression technique to
achieve high spatial densities (ideally up to
) in order to study new localization effects of light in
dense cloud of cold atoms.
