Nonlinear properties of dense coherent mediaMikhailov, Eugeniy Eugenievich 30 September 2004 (has links)
Properties of coherent media in the regime of
electromagnetically induced transparency (EIT)
are studied.
A study of the shape and width of the EIT resonance is presented
for coherent media with buffer gas.
Observation of an absorption-like resonance for large one-photon detunings in a medium with
buffer gas and its properties are shown.
The regime of ``slow'' and ``fast'' group velocities are studied.
Observation
of narrow resonances with a phase broadened probe field is presented,
and possible application of this regime are outlined.
