Opening four-wave mixing and six-wave mixing channels via dual electromagnetically induced transparency windows.
Highly efficient four-wave mixing (FWM) and six-wave mixing (SWM) processes can coexist in a four-level Y-type atomic system due to atomic coherence. 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 t...
متن کاملPerturbing an electromagnetically induced transparency in a system using a low-frequency driving field. II. Four-level system
The effect a perturbing field has on an electromagnetically induced transparency within a three-level system is presented. The perturbing field is applied resonant between one of the lower levels of the system and a fourth level. The electromagnetically induced transparency feature is split and this is measured experimentally for both single and bichromatic driving fields. In the single-driving...
متن کاملElectromagnetically induced spatial nonlinear dispersion of four-wave mixing
Spatial displacements of the probe and generated four-wave mixing beams are observed in a three-level V-type, as well as a two-level atomic system near resonance. The observed spatial shift curves reflect the typical enhanced cross-Kerr nonlinear dispersion properties in the electromagnetically induced transparency EIT systems. The spatial beam displacements are controlled by the strong control...
متن کاملObservations of Autler-Townes spatial splitting of four-wave mixing image
We report the selfand external-dressed AutlerTownes (A-T) splittings of the images of the generated four-wave mixing signal (FWM) and electromagnetically induced transparency (EIT) of probe images in cascade three-level atomic system. Such spatial properties of probe and FWM signals are induced by the enhanced cross-Kerr nonlinearity. We demonstrate the controlled electromagnetically induced sp...
متن کاملControlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
In this paper we examine the absorption and dispersion properties of a weak probe field via Electromagnetically Induced Transparency (EIT) in a four-level system. It is shown that under certain condition, using this model, the absorption cancellation is appeared and the medium becomes transparent to the weak probe field. It will be shown that the controlling of absorption and dispersion spectru...
