Abstract

We have experimentally studied electromagnetically induced transparency (EIT) and absorption (EIA) in hot 85Rb atomic vapor using probe and coupling light with comparable power levels. We have shown that strong-probe EIT has different linewidth and appears in fewer configurations than does usual, weak probe EIT. In V-scheme, where optical pumping and saturation are dominant mechanisms, narrow EIT is possible only when a probe is tuned to a closed transition. The width of the EIT resonance increases with laser intensity with non-linear dependence, similar to the weak-probe EIT in Λ- scheme. The EIT in Λ- scheme was observed when two transitions had balanced population losses. The EIA was modified for the case of a strong probe as well: in four-level N-scheme with Zeeman sublevels the EIA was observed only for a cycling transition when F’=F+1, where F and F’ are the angular momenta of the 5 2S1/2 (ground) and 5 2P3/2 (excited) state hyper-fine levels, respectively. The combination of strong probe and strong coupling laser beam intensities allows observation of an absorption dip due to three-photon resonance in a four-level scheme that involves the Raman transitions via virtual level.

Transmission spectra of the coupling laser locked to the F=2→F’=3 transition versus the probe laser detuning when the probe is scanned across the F=2→5 2P3/2 transition. Peaks 1–3 correspond to F’=1,2 and 3. Laser intensities are 18 mW/cm2 for the upper curve and 7 mW/cm2 for the middle curve (transmission multiplied by 6). The lower curve corresponds to the transmission of the coupling laser when the probe is blocked, or when the probe is far detuned from the resonance.
