Resumen en inglés

In this paper, we present a mathematical model for ultrashort pulses propagation in nonlinear optical crystals. For ultrashort pulses, classical models based on the slowly varying envelope approximation are no longer relevant. The microscopic model based on the Maxwell-Bloch model, that we present, can accurately describe the wave-propagation while accounting for dispersive nonlinearities. We will describe this model and its numerical discretization in two dimensions of space. Finally, we perform two numerical experiments.< Leer menos
