Paper Abstract

Electromagnetically induced transparency and absorption is observed in a transmission of the coupling laser, locked to transition between hyperfine levels of the ground and excited states of 85Rb. The transmission was monitored in a V, Λ and N-type systems while the probe laser, with similar power as the coupling laser, scans across the hyperfine levels F' of the 2P3/2. The measured width of the EIT resonance increases with a square-root dependence of laser intensity. The EIA was observed only for a cycling transition and for F' = F+1, where F and F' are the angluar momentum of the hyper-fine levels of the 2S1/2 and 2P3/2, respectively. We demonstrated the effect of a three-photon EIA in a four-level scheme that involves the Raman transitions via virtual level.
