Behavior of a very large magneto-optical trap

Abstract

We investigate the scaling behavior of a very large magneto-optical trap (VLMOT) containing up to $1.4\times 10^{11}$ Rb${}^{87}$ atoms. By varying the diameter of the trapping beams, we are able to change the number of trapped atoms by more than 5 orders of magnitude. We then study the scaling laws of the loading and size of the VLMOT, and analyze the shape of the density profile in this regime where the Coulomb-like, light-mediated repulsive interaction between atoms is expected to play an important role.
