A novel optical pumping method is developed to reduce the light shift (AC Stark shift) in a vapor cell atomic frequency standard. The method uses the multiple excited state energy levels to cancel the total light shift. The collision-broadened linewidth in the optical transition is used to reduce the resultant influence of the laser frequency detuning… (More)
