Measurement of the Zeeman-like ac Stark shift

The formation of Stark effect into Zeeman effect due to the circular polarization of lasers and detuning properties of alkali metals was described. Atomic beam resonance methods including optical pumping and Raman excitation was used to detect slow atomic beams. The application of Zeeman-like ac Stark shift in optical manipulation of atomic motion was also demonstrated. It was shown that when laser light was circularly polarized and properly detuned, the ac Stark shift of an alkali-metal atom in its ground state takes the form of a pure Zeeman shift.
