Electromagnetically induced transparency controlled by a microwave field (2009)
Li, Hebin, Sautenkov, Vladimir A., Rostovtsev, Yuri V., Welch, George R., Hemmer, Philip R., Scully, Marlan O.
We have experimentally studied propagation of two optical fields in a dense rubidium (Rb) vapor in the case when an additional microwave field is coupled to the hyperfine levels of Rb atoms. The Rb...
Vapor pressure dependence of spectral width of EIT in Lambda-level cesium molecular system (2009)
Chen, Hui, Li, Hebin, Rostovtsev, Yuri V., Gubin, Mikhail A., Sautenkov, Vladimir A., Scully, Marlan O.
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-resonance in an...
Excitation dependence of resonance line self-broadening at different atomic densities (2008)
Li, Hebin, Sautenkov, Vladimir A., Rostovtsev, Yuri V., Scully, Marlan O.
We study the dipole-dipole spectral broadening of a resonance line at high atomic densities when the self-broadening dominates. The selective reflection spectrum of a weak probe beam from the...
Atomic noise spectra in nonlinear magneto-optical rotation in a rubidium vapor (2008)
Li, Hebin, Sautenkov, Vladimir A., Varzhapetyan, Tigran S., Rostovtsev, Yuri V., Scully, Marlan O.
We have studied the noise spectra in a nonlinear magneto-optical rotation experiment in a rubidium vapor. We observed the reduction of noise in the intensity difference of two orthogonally polarized...
Intensity correlations in resonance nonlinear magneto-optical rotation (2008)
Varzhapetyan, Tigran S., Li, Hebin, Ariunbold, Gombojav O., Sautenkov, Vladimir A., Rostovtsev, Yuri V., Scully, Marlan O.
We have studied the intensity correlations between two orthogonally linearly polarized components of a laser field propagating through a resonant atomic medium. These experiments have been performed...
Optical imaging beyond the diffraction limit via dark states (2008)
Li, Hebin, Sautenkov, Vladimir A., Kash, Michael M., Sokolov, Alexei V., Welch, George R., Rostovtsev, Yuri V., ...
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 optical fields...
Ultra-dispersive adaptive prism (2007)
Sautenkov, Vladimir A., Li, Hebin, Rostovtsev, Yuri V., Scully, Marlan O.
We have experimentally demonstrated an ultra-dispersive optical prism made from coherently driven Rb atomic vapor. The prism possesses spectral angular dispersion that is six orders of magnitude...
