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

Electromagnetically induced transparency in rubidium
American Journal of Physics, 2009We investigate ladder-type electromagnetically induced transparency (EIT) in rubidium gas. The theoretical absorption profile of a weak probe laser beam at 780.2nm (5S1∕2→5P3∕2) is modeled in the presence of a strong coupling laser beam at 776.0nm (5P3∕2→5D5∕2) and the absorption transparency window is characterized.

Electromagnetically induced transparency in nanocells
Journal of Physics B: Atomic, Molecular and Optical Physics, 2009The formation of the electromagnetically induced transparency (EIT) resonance in nanocells is considered. It is shown that the Dicke narrowing of the optical transition takes place in nanocells with the wall coating providing the specular reflection of atoms. The width of the EIT resonance can reach some hundreds of hertz in such cells.

Noise and Electromagnetically Induced Transparency
Frontiers in Optics 2007/Laser Science XXIII/Organic Materials and Devices for Displays and Energy Conversion, 2007We report coherence-induced conversion of laser phase noise to intensity noise via interaction with an atomic medium. The spectrum of intensity fluctuations exhibits a narrow linewidth, that is immune to power broadening.

Phase-dependent electromagnetically induced transparency
Physical Review A, 1999We report on the experimental demonstration of phase-dependent electromagnetically induced transparency (EIT). This effect is based on a quantum interference in closed-loop schemes of interaction of atoms with the radiation. It allows us to control optical properties of the medium by the phases of the laser fields.
