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 ...
Optically controlled delays for broadband pulses
(American Physical Society, 2005)
We propose a scheme that provides large controllable delays for broadband optical pulses. The system is based on the steep dispersion of a coherently driven medium, in which the narrow electromagnetically induced transparency ...
