“…All EIT applications require a detailed understanding about the EIT line-shape. Recently, experimental observations of EIT in laser-cooled atoms [12,[15][16][17][18] have gathered immense importance due to its several advantages. The absence of Doppler broadening in the sub-mK temperature range helps to perform high resolution spectroscopic studies.…”

Variations of the coherent resonance, i.e. an electromagnetically induced transparency (EIT) peak with the cell temperature in -and V-type systems are observed for the 85 Rb-D 2 transition. In a -type system, the amplitude of the EIT peak gradually decreases and it is finally masked by the broadened optical pumping dips with the increase of the cell temperature. But for the V-type system, the EIT and the saturation peaks are greatly enhanced with the increase of the cell temperature. The effect of the external magnetic field on the EIT resonance is also investigated considering both types of systems. For the -type system in place of a single EIT resonance, five transparency windows with broadened width and reduced contrast are obtained depending on the Zeeman levels formed by the applied magnetic field. In the V-type system, the coherent resonance peak could not be resolved in the presence of the external magnetic field, but a greater number of saturation peaks with broadened width appear in the probe transmission spectrum. A theoretical model is adopted to represent the experimental results. Good agreement is found between the experimental and numerically simulated results.

“…Since its first experimental realization in 1991 by Boller et al [2] in strontium vapour, the phenomenon of EIT has been instrumental in the progress of various fields, such as nonlinear optics [3][4][5], sensitive magnetometry [6], Rydberg states spectroscopy [7,8] and laser frequency stabilization [9,10]. Mostly, these EITrelated studies have been carried out either using Doppler-free configuration of coupling and probe beams in an atomic vapour cell [11][12][13] or in an inherently Doppler-free environment of cold atoms [14][15][16]. The elimination of the Doppler broadening effect and low collisional dephasing rate has made the cold atoms an attractive medium to explore the EIT effect with moderate coupling beam intensities [17].…”

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.

We report experimental studies of electro magnetically induced transparency and enhancement of third‐order optical nonlinearities in A‐type atomic systems realized in 87Rb atoms cooled and confined in a magneto‐optical trap. We observed complete transparency of a weak probe laser in the A type Rb system with a moderate coupling field. With a third pump laser tuned to a fourth atomic state, the atomic system exhibits the interference‐enhanced third‐order susceptibility and only absorbs two photons, but not one photon. Our experiment demonstrates large nonlinear absorption of the weak probe laser, from which greatly enhanced Kerr nonlinearity in the Rb system is inferred.
