Title: Coherent accumulation of excitation in the electromagnetically induced transparency of an ultrashort pulse train
Author: Soares, AA

Abstract: We investigate the excitation of an atomic degenerate-Lambda system by a train of ultrashort pulses. An iterative analytic solution to the optical Bloch equations is found describing the temporal evolution of the density matrix elements. We show that electromagnetically induced transparency of the excitation pulses develops through the coherent accumulation of excitation (population and coherence) between the degenerate lower states. The influence of the pulse train parameters (area, repetition period, and phase between successive pulses) on establishing the transparency is investigated.
