Controlling of Absorption and Dispersion Spectrum via Electromagnetically Induced Transparency
نویسندگان: ثبت نشده
چکیده مقاله:
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 spectrum depends on some atomic parameters. The effects of quantum interference on the absorption and dispersion spectrum are also investigated

متن کاملParametric dispersion in electromagnetically induced transparency
We analyze both experimentally and theoretically the phase shift of a fixed coupling laser field in a L-type system induced by a tunable probe laser field. The measurements are performed with a heterodyne interferometer on a beam of cesium atoms in the D2 line. This system exhibits electromagnetically induced transparency with a rapidly varying refractive index. The parametric dispersion of the...
متن کاملSwitching from "absorption within transparency" to "transparency within transparency" in an electromagnetically induced absorption dominated transition.
The absorption of a resonant coupling laser driving a closed degenerate two-level system in an atomic cesium beam was investigated as a function of the detuning of a second laser probing the same transition. The measurements were performed for four different polarization combinations of the two laser beams. Except for the beams of counterrotating polarizations all coupling-laser absorption prof...
متن کاملElectromagnetically Induced Transparency in 6 Li Electromagnetically Induced Transparency In
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 f...
متن کاملHeterodyne measurement of parametric dispersion in electromagnetically induced transparency
Using three phase-locked lasers, we have observed in a three-level system the phase shift of the frequency fixed coupling laser in dependence of the probe laser frequency relative to an off-resonant reference laser. In the vicinity of the two-photon resonance, the system exhibits electomagnetically induced transparency and we show that the dispersion of coupling and probe field shows different ...
