Vapor pressure dependence of spectral width of EIT in Lambda-level cesium molecular system
Hui Chen, Hebin Li, Yuri V. Rostovtsev +3
We have studied electromagnetically induced transparency (EIT) in diatomic cesium molecules in a vapor cell by using tunable diode lasers. We have observed a sub-natural Lambda-res…
Optical imaging beyond the diffraction limit via dark states
Hebin Li, Vladimir A. Sautenkov, Michael M. Kash +5
We study the possibility of creating spatial patterns having subwavelength size by using the so-called dark states formed by the interaction between atoms and optical fields. These…
From EIT photon correlations to Raman anti-correlations in coherently prepared Rb vapor
Vladimir A. Sautenkov, Yuri V. Rostovtsev, Marlan O. Scully
We have experimentally observed switching between photon-photon correlations (bunching) and anti-correlations (anti-bunching) between two orthogonally polarized laser beams in an E…
Ultra-Slow Light and Enhanced Nonlinear Optical Effects in a Coherently Driven Hot Atomic Gas
Michael M. Kash, Vladimir A. Sautenkov, Alexander S. Zibrov +6
We report the observation of small group velocities of order 90 meters per second, and large group delays of greater than 0.26 ms, in an optically dense hot rubidium gas (~360 K).…
