Abstract: | As it is known 1] an intense laser field can induce atom-atom interaction according to a dipole-dipole R
–3 law. Such an interaction depends on the angle between light polarization and interatomic vector-position R. This angular dependence may produce an anisotropy in the spatial density distribution of the confined sample of cold atoms. We develop the main relations and apply them to the case of an atomic cloud of cold trapped neutral atoms with the density higher than or of the order of –3, where is the wavelength of light. The results presented here show the effect of such an interaction in a density regime of high experimental interest. |
