AC-Stark shift and photoionization of Rydberg atoms in an optical dipole trap
Abstract
We have measured the AC-Stark shift of the 14D5/2 Rydberg state of rubidium 87 in an optical dipole trap formed by a focussed CO2-laser. We find good quantitative agreement with the model of a free electron experiencing a ponderomotive potential in the light field. In order to reproduce the observed spectra we take into account the broadening of the Rydberg state due to photoionization. The extracted cross-section is compatible with previous measurements on neighboring Rydberg states.
