Electromagnetically Induced Transparency in 6 Li Electromagnetically Induced Transparency In

چکیده
We report electromagnetically induced transparency for the D1 and D2 lines in 6 Li in both a vapour cell and an atomic beam. Electromagnetically induced transparency is created using co-propagating mutually coherent laser beams with a frequency difference equal to the hyperfine ground state splitting of 228.2 MHz. The effects of various optical polarization configurations and applied magnetic fields are investigated. In addition, we apply an optical Ramsey spectroscopy technique which further reduces the observed resonance width.

Controlling 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...
متن کاملThe Effect of Antenna Movement and Material Properties on Electromagnetically Induced Transparency in a Two-Dimensional Metamaterials
Increasing development of nano-technology in optics and photonics by using modern methods of light control in waveguide devices and requiring miniaturization and electromagnetic devices such as antennas, transmission and storage as well as improvement in the electromagnetic tool, have led researchers to use the phenomenon of electromagnetically induced transparency (EIT) and similar phenomena i...
متن کاملObservation of electromagnetically induced transparency in two - photon transitions of 39 K 2
Electromagnetically induced transparency has been observed in K2 two-photon transitions by fluorescence detection. The twophoton absorptions correspond to 2Pg XRg transitions through ARu bPu mixed intermediate enhancing levels, which are coincidentally on resonance with the excitation laser frequency. Laser intensity dependence of this effect has been studied and different detection schemes hav...
متن کاملDouble Electromagnetically Induced Transparency in a Tripod-type Atom System
The electromagnetically induced transparency (EIT) phenomenon in a four level atomic system with tripod configuration is studied. The results show that this configuration is equivalent to the combination of two single three-level Λ configurations, which, under certain conditions, results in the so-called double-EIT (DEIT) phenomenon. The properties of the double transparency windows for DEIT ar...
متن کاملWhat is and what is not electromagnetically induced transparency in whispering-gallery microcavities.
There has been an increasing interest in all-optical analogues of electromagnetically induced transparency and Autler-Townes splitting. Despite the differences in their underlying physics, both electromagnetically induced transparency and Autler-Townes splitting are quantified by a transparency window in the absorption or transmission spectrum, which often leads to a confusion about its origin....
