Abstract

We present the theoretical framework and the approximations needed to numerically simulate the response of alkali metal atoms under multi-photon excitation. By applying the semi-classical approximation, we obtain a system of coupled ordinary and partial differential equations accounting both for the nonlinear dynamics of the atomic medium and the spatiotemporal evolution of the emitted fields. The case of two-photon excitation by a laser field with an additional one-photon coupling field is investigated by numerically solving the set of differential equations employing a self-consistent computational scheme. The computation of the emission intensities and atomic level populations and coherences is then possible.
