Gp. Djotyan et al., Population transfer in three-level Lambda atoms with Doppler-broadened transition lines by a single frequency-chirped short laser pulse, J OPT SOC B, 17(1), 2000, pp. 107-113
We examine interaction of a single frequency-chirped laser pulse with three
-level atoms that have a Lambda configuration of levels. We show that it is
possible to produce complete fast and robust population transfer of all at
oms of the ensemble with Doppler-broadened transition lines from one ground
state into the other ground state with negligibly small temporary populati
on of the excited state by controlling the intensity of the laser pulse and
the direction and speed of the frequency chirp. (C) 2000 Optical Society o
