In this article, the experimental observations of double EIT and enhanced EIT signal in a combination of Λ- and V-type multi-level system of the D2 transition of 85Rb atoms interacting with three laser fields are reported.Abstract:
We report the experimental observations of double EIT and enhanced EIT signal in a combination of Λ- and V-type multi-level system of the D2 transition of 85Rb atoms interacting with three laser fields. The EIT formation under a Λ-type and V-type systems is also observed separately. It is found that the EIT width in a V-type system becomes narrower than the Λ-type system. Also the effect of frequency detuning of the control laser on the probe absorption profile is studied in presence of Λ- and V-type EIT systems.read more

Electromagnetically induced transparency : Optics in coherent media
TL;DR: In this paper, the authors consider the atomic dynamics and the optical response of the medium to a continuous-wave laser and show how coherently prepared media can be used to improve frequency conversion in nonlinear optical mixing experiments.

Observation of electromagnetically induced transparency.
TL;DR: In this paper, the authors report the first demonstration of a technique by which an optically thick medium may be rendered transparent by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent.

Observation of electromagnetically induced transparency
TL;DR: The first demonstration of a technique by which an optically thick medium may be rendered transparent is reported, which results from a destructive interference of two dressed states created by applying a temporally smooth coupling laser between a bound state of an atom and the upper state of the transition which is to be made transparent.

Opening four-wave mixing and six-wave mixing channels via dual electromagnetically induced transparency windows.
TL;DR: The simultaneously opened dual electromagnetically induced transparency windows in this four-level atomic system allow observation of these two nonlinear optical processes at the same time, which enables detailed studies of the interplay between the FWM and SWM processes.
