Excitation dependence of resonance line self-broadening at different atomic densities
Hebin Li, Vladimir A. Sautenkov, Yuri V. Rostovtsev +1
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 be…
Quantum Interferences in Cooperative Dicke Emission from Spatial Variation of Laser Phase
Sumanta Das, G. S. Agarwal, Marlan O. Scully
We report generation of a new quantum interference effect in spontaneous emission from a resonantly driven system of two identical two-level atoms due to the spatial variation of t…
Atomic noise spectra in nonlinear magneto-optical rotation in a rubidium vapor
Hebin Li, Vladimir A. Sautenkov, Tigran S. Varzhapetyan +2
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 orth…
Intensity correlations in resonance nonlinear magneto-optical rotation
Tigran S. Varzhapetyan, Hebin Li, Gombojav O. Ariunbold +3
We have studied the intensity correlations between two orthogonally linearly polarized components of a laser field propagating through a resonant atomic medium. These experiments h…
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…
