We theoretically study the stacked optical transients generated from a series of square
pulses passing through a cold atomic ensemble. Using the hybrid analysis and fast Fourier …

We report the generation of stacked optical precursors from a laser beam whose amplitude
or phase is modulated by sequenced on-off step waveforms. Making use of the constructive …

We report results of both theoretical and experimental studies of optical precursors
generated from a square-modulated probe laser pulse having a finite rise and fall time and …

We report the observation of Sommerfeld-Brillouin optical precursors generated from a long
square-modulated laser pulse propagating through a cold atomic ensemble with …

This work presents a theoretical study of two coherent schemes which allow the
manipulation of wave packets created in atomic systems by strong ultrashort pulses. Our …

We study the effects of propagation through an extended sample of two-and three-level
atoms on the coherent accumulation of excitation by an ultrashort pulse train. In the two-level …

A theoretical analysis of the optical coherent transients that arise when a sample of two-level
atoms is irradiated by a sequence of three broad-bandwidth pulses is presented. The first …

We investigate the excitation of an atomic degenerate-Λ system by a train of ultrashort
pulses. An iterative analytic solution to the optical Bloch equations is found describing the …

Slow light, produced in a medium with two widely spaced absorption resonances, is
analytically studied. We show that a pulse with frequency tuned in the middle of such a …

We have studied stationary and quasistationary signal light pulses in cold Λ-type atomic
media driven by counterpropagating control laser fields at the condition of …
