ELECTROMAGNETICALLY INDUCED TRANSPARENCY
Optics and Photonics News, 1991Electromagnetically induced transparency is a technique for eliminating the effect of a medium on a propagating beam of electromagnetic radiation. EIT may also be used, but under more limited conditions, to eliminate optical self-focusing and defocusing and to improve the transmission of laser beams through inhomogeneous refracting gases and metal ...

Self-induced transparency assisted by electromagnetically induced transparency
Physical Review A, 2006We show the possibility of transparency and soliton effects for an intense pulse propagating in a V-type medium in which two upper resonant sublevels experience fast field-induced decay due to incoherent coupling to an upper lying state or continuum.

Electromagnetically Induced Transparency
1996Electromagnetically induced transparency (EIT) is a technique for making an otherwise optically-thick medium transparent to laser radiation.’ The basic idea is to use two lasers or electromagnetic fields whose frequency difference is equal to a Raman (or two-photon) transition of the atom or molecule.

Dispersive properties of electromagnetically induced transparency
Physical Review A, 1992An atomic transition that has been made transparent by applying an additional electromagnetic field exhibits a rapidly varying refractive index with zero group velocity dispersion at line center. A 10-cm-long Pb vapor cell at an atom density of 7\ifmmode\times\else\texttimes\fi{}${10}^{15}$ atoms/${\mathrm{cm}}^{3}$ and probed on its 283-nm resonance ...

Preparation energy for electromagnetically induced transparency
Physical Review A, 1995We discuss a requirement for the laser energy that is necessary to initiate electromagnetically induced transparency: The number of photons in the coupling laser pulse must exceed the product of the number of atoms in the laser path times the ratio of the oscillator strengths of the probe and coupling laser transitions.

Electromagnetically induced transparency
20051. Electromagnetically induced transparency (EIT) describes a phenomenon by which an opaque optical medium becomes transparent due to quantum interference effects. 2. EIT has been observed in atomic, molecular and solids media. 3. EIT has been widely employed to control light wave propagation, including control of the refractive index and enhancement ...

Electromagnetically Induced Transparency with Squeezed Vacuum
Physical Review Letters, 2004The squeezed vacuum resonant on the (87)Rb D1 line (probe light) was injected into an optically dense rubidium gas cell with a coherent light (control light). The output probe light maintained its quadrature squeezing within the transparency window caused by the electromagnetically induced transparency (EIT).

Electromagnetically induced transparency with quantum interferometry
The Journal of Chemical Physics, 2012We have shown that electromagnetically induced transparency can be achieved by control-probe interferometry using two delayed phase-locked ultrashort pulses. Two vibrational wavepackets on the excited state, excited by two delayed phase-locked ultrashort pulses, interfere constructively or destructively leading to enhancement or suppression of ...

Nonlinear optical processes using electromagnetically induced transparency
Physical Review Letters, 1990It is well known by those practicing the techniques of nonlinear optics that the power that may be generated in a frequency summing process and the gain that may be obtained in a parametric process are determined by the interaction of tire nonlinear and linear susceptibilities.

Electromagnetic Induced Transparency
2016Three-level atomic and molecular systems coupled to two laser fields exhibit transparency effects that result from the cancellation of absorption at a resonance transition frequency. These effects are deliberately induced by one of the two laser fields upon modifying the medium optical response to the other field. The large degrees of transparency in a
