Abstract
A numerical study of coherent laser pulse evolution in CO2 in the framework of the Maxwell–Schrödinger equations up to the intensity 1013 W/cm2 is presented. The model includes various nonresonant vibrational–rotational transitions usually neglected in low-intensity simulations. Level degeneracy is taken into account, and light-polarization effects are discussed. The limiting intensities up to which various models work are established.
