Journal ArticleDOI
Efficient light storage in a crystal using an Atomic Frequency Comb
TL;DR: In this article, an atomic frequency comb (AFC) was used to map a light field onto a thulium-doped crystal using an accurate spectral preparation of the sample.
Journal ArticleDOI
Observation of ultra-narrow electromagnetically induced transparency and slow light using purely electronic spins in a hot atomic vapor
Fabienne Goldfarb,Joyee Ghosh,Joyee Ghosh,M. David,J. Ruggiero,Thierry Chanelière,J.-L. Le Gouët,H. Gilles,Rupamanjari Ghosh,Fabien Bretenaker +9 more
TL;DR: In this article, the EIT windows were obtained for purely electronic spins in the presence of Doppler broadening and the positive role of collisions was emphasized through measurements of the power dependence of EIT resonance.

Observation of Ultra-narrow Electromagnetically Induced Transparency and Slow Light using Purely Electronic Spins in a Hot Atomic Vapor
Fabienne Goldfarb,Joyee Ghosh,Joyee Ghosh,M. David,J. Ruggiero,Thierry Chanelière,J.-L. Le Gouët,H. Gilles,Rupamanjari Ghosh,Fabien Bretenaker +9 more
TL;DR: In this article, the EIT windows were obtained for purely electronic spins in the presence of Doppler broadening and the positive role of collisions was emphasized through measurements of the power dependence of EIT resonance.
Journal ArticleDOI
Electromagnetically-induced transparency, slow light, and negative group velocities in a room temperature vapor of 4He∗
TL;DR: Goldfarb et al. as discussed by the authors showed that it is possible to use optically detuned resonances (Fano-like profiles) to see a transition from slow light to negative group velocity.
Journal ArticleDOI
Observation of electromagnetically induced transparency and slow light in the dark state--bright state basis.
TL;DR: The characteristics of EIT, namely, width of the transmission window and reduced group velocity of light, in this unusual basis, are theoretically and experimentally investigated and are shown to be essentially identical to those of standard EIT in the same system.
