Spectral narrowing via quantum coherence
(American Physical Society, 2006)
We have studied the transmission through an optically thick Rb-87 vapor that is illuminated by monochromatic and noise-broadened laser fields in Lambda configuration. The spectral width of the beat signal between the two ...
Electromagnetically induced transparency in rubidium vapor prepared by a comb of short optical pulses
(American Physical Society, 2005)
It was shown by Kocharovskaya and Khanin [Sov. Phys. JETP 63, 945 (1986)] that a comb of optical pulses can induce a ground-state atomic coherence and change the optical response of an atomic medium. In our experiment, we ...
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 ...
