Zibrov, Sergei A., Novikova, Irina, Phillips, David F., Walsworth, Ronald L., Zibrov, Alexander S., Velichansky, Vladimir L., ...
We present a joint theoretical and experimental characterization of the coherent population trapping (CPT) resonance excited on the D1 line of 87Rb atoms by bichromatic linearly polarized laser...
Realization of Coherent Optically Dense Media via Buffer-Gas Cooling (2008)
Hong, Tao, Gorshkov, Alexey V., Patterson, David, Zibrov, Alexander S., Doyle, John M., Lukin, Mikhail D., ...
We demonstrate that buffer-gas cooling combined with laser ablation can be used to create coherent optical media with high optical depth and low Doppler broadening that offers metastable states with...
Comparison of 87Rb N-resonances for D1 and D2 transitions (2006)
Novikova, Irina, Phillips, David F., Zibrov, Alexander S., Walsworth, Ronald L., Taichenachev, Alexksei V., Yudin, Valeriy I.
We report an experimental comparison of three-photon-absorption resonances (known as "N-resonances") for the D_1 and D_2 optical transitions of thermal 87Rb vapor. We find that the D_2 N-resonance...
Cancellation of light-shifts in an N-resonance clock (2005)
Novikova, Irina, Taichenachev, Alexei V., Yudin, Valery I., Phillips, David F., Zibrov, Alexander S., Walsworth, Ronald L.
We demonstrate that first-order light-shifts can be cancelled for an all-optical, three-photon-absorption resonance ("N-resonance") on the D1 transition of Rb87. This light-shift cancellation enables...
Observation of polarization quantum noise of laser radiation in Rb vapor cell (2005)
Zibrov, Alexander S., Novikova, Irina
We present experimental study of polarization quantum noise of laser radiation passed through optically think vapor of Rb87. We observe a step-like noise spectrum. We discuss various factor which may...
A novel absorption resonance for all-optical atomic clocks (2005)
Zibrov, Sergei, Novikova, Irina, Phillips, David F., Taichenachev, Aleksei V., Yudin, Valeriy I., Walsworth, Ronald L., ...
We report an experimental study of an all-optical three-photon-absorption resonance (known as a "N-resonance") and discuss its potential application as an alternative to atomic clocks based on...
Ultra-Slow Light and Enhanced Nonlinear Optical Effects in a Coherently Driven Hot Atomic Gas (1999)
Kash, Michael M., Sautenkov, Vladimir A., Zibrov, Alexander S., Hollberg, L., Welch, George R., Lukin, Mikhail D., ...
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). Media of this kind...
