Propagation of High-Power, Femtosecond Laser Radiation through the Atmosphere
Abstract
This report results from a contract tasking the Institute of Atmospheric Optics, Siberian Branch, as follows: the contractor will investigate theoretically the interaction between femtosecond propagation effects and atmospheric turbulence, supercontinuum emission (spectral broadening), nonlinear scattering by atmospheric aerosols, and theoretical upper and lower limits for nonlinear propagation effects. The specific project objectives are as follows: (1) The theoretical study of powerful femtosecond laser pulse filamentation in the turbulent atmosphere; (2) Researching the supercontinuum cone emission mechanism by numerical simulation of high-power femtosecond laser pulse propagation in the atmosphere; and (3) The theoretical and experimental study of the fundamental problems of scattering of a high-power femtosecond pulse in the atmosphere: nonstationary light scattering in gases and aerosols; nonlinear inelastic nonstationary light scattering by aerosol particles.
