Light assisted collisions. The graph shows the probability of Cs atoms surviving a 1.3 s MOT period while a cold Rb cloud is present in the dipole trap crossing region in dependence of the crossing region’s position along the horizontal dipole trap beam. We attribute the losses to light assisted collisions of Cs with Rb in the presence of near resonant Cs MOT light. A negative Gaussian fit (red) serves as a guide to the eye.
