Buffer-gas-induced absorption resonances in Rb vapor RID B-9041-2008
(American Physical Society, 2004)
We observe transformation of the electromagnetically induced transparency (EIT) resonance into an absorption resonance in a Lambda interaction configuration in a cell filled with Rb-87 and a buffer gas. This transformation ...
Enhancement of magneto-optic effects via large atomic coherence in optically dense media RID B-9041-2008
(American Physical Society, 2000)
We utilize the generation of large atomic coherence in optically dense media to enhance the resonant nonlinear magneto-optic effect by several orders of magnitude, thereby eliminating power broadening and improving the ...
Large negative and positive delay of optical pulses in coherently prepared dense Rb vapor with buffer gas RID B-9041-2008
(American Physical Society, 2004)
We experimentally study the group time delay for a light pulse propagating through hot Rb-87 vapor in the presence of a strong coupling field in a Lambda configuration. We demonstrate that the ultraslow pulse propagation ...
Vacuum squeezing in atomic media via self-rotation RID A-1272-2007 RID B-9041-2008
(American Physical Society, 2002)
When linearly polarized light propagates through a medium in which elliptically polarized light would undergo self-rotation, squeezed vacuum can appear in the orthogonal polarization. A simple relationship between self-rotation ...
Compensation of ac Stark shifts in optical magnetometry RID B-9041-2008 RID A-1272-2007
(American Physical Society, 2001)
The ac Stark shift of the resonance frequency of the nonlinear magneto-optic effect (NMOE) results in a fundamental broadening of this resonance which limits the precision of optical magnetometry based on NMOE. We have ...
Nonlinear magneto-optical rotation of elliptically polarized light RID A-1272-2007 RID B-9041-2008
(American Physical Society, 2003)
We predict theoretically and demonstrate experimentally an ellipticity-dependent nonlinear magneto-optic rotation of elliptically polarized light propagating in a medium with atomic coherence. We show that this effect ...
