Miro´: Complete modeling and software for pulse amplification and propagation in high-power laser systems

Abstract

This paper presents some of the most important features of the MirO code, which is a laser propagation program for high-peak-power laser setups. The main propagation models are discussed: the paraxial nonlinear Schrodinger approximation, broadband computation including dispersion effects, and spatial and temporal Talanov transforms are described, as well as the main optical components: a four-level multipass amplifier including both saturation and narrowing effects; broadband and noncollinear frequency conversion; the grating, including high-order dispersion effects; and laser damage effects. Some elementary examples of MirO computation are also provided.
