| Abstract: | We demonstrate a technique for directly measuring the quadratic Zeeman shift using stimulated Raman transitions. The quadratic Zeeman shift has been measured yielding Δν=1296.8±3.3 Hz/G2 for magnetically insensitive sublevels (5S1/2,F=2,mF=0→5S1/2,F=3,mF=0) of 85Rb by compensating the magnetic field and cancelling the ac Stark shift. We also measured the cancellation ratio of the differential ac Stark shift due to the imbalanced Raman beams by using two pairs of Raman beams (σ+, σ+) and it is 1:3.67 when the one-photon detuning is 1.5 GHz in the experiment. |
