Abstract
We report our study of the optical pumping effect in absorption imaging of Na23 atoms in the F=1 hyperfine spin states. Solving a set of rate equations for the spin populations in the presence of a probe beam, we obtain an analytic expression for the optical signal of the F=1 absorption imaging. Furthermore, we verify the result by measuring the absorption spectra of Na23 Bose-Einstein condensates prepared in various spin states with different probe-beam pulse durations. The analytic result can be used in the quantitative analysis of F=1 spinor condensate imaging and readily applied to other alkali-metal atoms with I=3/2 nuclear spin such as Rb87. © 2016 American Physical Society
