Abstract :
We develop a model for optically trapped states including Zeeman coherences to show that their number depends only on the change in F (hyperfine state) during the transition and is independent of the polarization or the coordinate system. Using a polarization switching technique, we achieve complete optical pumping even in the small magnetic field used in our primary standard.<>
