(a) Off-resonant coupling of a 2S1/2 ground state manifold to a 2P1/2 excited state manifold with polarized light. (b) Hyperfine levels of the ground state manifold when the nuclear spin is I=1. The states are labelled |F,mF›, where F is the total angular momentum, and mF is the projection of the total angular momentum on the z axis. The choice of blue and red spin up and down states is indicated.
