Observing the Polarization Dependent Light Shifts Using an Atom Fountain

Abstract

Abstract We theoretically predicted and experimentally demonstrated the sinusoidal shifts of the 87Rb atom Raman transition frequencies as the polarization vectors of the Raman lasers rotate. We also presented the vanish of the differential light shifts for the magnetic sensitive Raman transitions at some elliptically polarized configurations while no vanish for the magnetic insensitive Raman transition. These results are helpful for the evaluation and elimination of the light shifts induced systemic errors in the atomic magnetometer, atomic interferometer, atomic clock and quantum computing.
