Electromagnetically induced transparency in cold 85Rb atoms trapped in the ground hyperfine F = 2 state

Abstract

We report electromagnetically induced transparency (EIT) in cold 85Rb atoms, trapped in the lower hyperfine level F = 2, of the ground state 5${}^2{S}_{1/2}$ (Tiwari V B \textit{et al} 2008 {\it Phys. Rev.} A {\bf 78} 063421). Two steady state $\Lambda$-type systems of hyperfine energy levels are investigated using probe transitions into the levels F${}^{\prime }$ = 2 and F${}^{\prime }$ = 3 of the excited state 5${}^2{P}_{3/2}$ in the presence of coupling transitions F = 3 $\to$ F${}^{\prime }$ = 2 and F = 3 $\to$ F${}^{\prime }$ = 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.
