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 ...
