Wide-beam high-power femtosecond pulse propagation in air

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

Large-scale computer simulations of wide-beam, high-power femtosecond laser pulse propagation in air are presented. Our model, based on the nonlinear Schrodinger equation for the vector field, incorporates the main effects present in air, including diffraction, group-velocity dispersion, absorption and defocusing due to plasma, multiphoton absorption, nonlinear self-focusing and rotational stimulated Raman scattering. The field equation is coupled to a model that describes the plasma density evolution. Intense femtosecond pulses with powers significantly exceeding the critical power for self-focusing in air are simulated to study turbulence-induced filament formation, their mutual interaction via a low-intensity background, dynamics of the field polarization, and evolution of the polarization patterns along the propagation direction.
