Birefringence in electromagnetically induced transparency

Optics Letters, 1997
(4)He 2 (3)S(1) --> 2 (3)P transitions at 1083 nm were laser probed in the presence of radiation that coupled the 2 (3)P level with the 3 (3)S(1) level in a ladder scheme. The metastable helium that was used was produced in a rf discharge. Significant atomic birefringence was detected, in addition to complete electromagnetically induced transparency. A

Electromagnetically induced transparency

Journal of Modern Optics, 1998
Abstract The subject of electromagnetically induced transparency (EIT) is reviewed in this paper. Emphasis is placed on the experimental work reported in this field since 1990. Theoretical work is also covered, although it is not intended to review all the very numerous recent theoretical treatments on this topic.

Electromagnetically Induced Transparency: Propagation Dynamics

Physical Review Letters, 1995
We describe the temporal and spatial dynamics of propagating electromagnetically induced transparency pulses in an optically thick medium. Results include pulse velocities as slow as $c/165$ with 55% transmission, strong-probe-field effects, and the observation of near diffraction-limited transmitted beam quality.

ELECTROMAGNETICALLY INDUCED TRANSPARENCY

Optics and Photonics News, 1991
Electromagnetically 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, 2006
We 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

1996
Electromagnetically 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, 1992
An 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 ...
