“…The results clearly show that the EIT signal from a Λ-type system involving hyperfine levels depends on the Zeeman sublevels of the common excited state. We expect that our alternative experimental scheme to obtain a steady-state Λ-type EIT system with cold atoms in the lower hyperfine level may find interest in the experiments related to light pulse storage [35] and optical switching devices with cold atoms [36,37].…”

We report electromagnetically induced transparency (EIT) in cold 85 Rb atoms, trapped in the lower hyperfine level F = 2, of the ground state 5 2 S 1/2 (Tiwari V B et al 2008 Phys. Rev. A 78 063421). Two steady state Λ-type systems of hyperfine energy levels are investigated using probe transitions into the levels F ′ = 2 and F ′ = 3 of the excited state 5 2 P 3/2 in the presence of coupling transitions F = 3 → F ′ = 2 and F = 3 → F ′ = 3, respectively. The effects of uncoupled magnetic sublevel transitions and coupling field's Rabi frequency on the EIT signal from these systems are studied using a simple theoretical model.
