Coherent Excitation of Two-Level Atoms by Pulse Trains
Interaction of a two-state system with a train of short pulses has attractive applications in various areas of atomic and molecular physics, such as sub-natural linewidth spectroscopy. We present a non-perturbative analytical study of coherent excitation of a two-state system by N consecutive equally spaced identical pulses. Assuming that relaxation is not present or can be neglected we have derived general closed-form relations between the evolution-matrix elements in the cases of one and N pulses.
