Abstract

A mathematical model of plasma dynamics of a laser-induced filament supported and controlled by a direct current discharge has been developed. The model we present includes Navier-Stokes, electron and vibrational temperature equations, plasma-kinetic and combustion-kinetic equations, as well as the Boltzmann equation for the electron energy distribution function. It was used to model plasma dynamics of a spark discharge guided by a femtosecond laser filament in air and methane-air mixtures. The calculated electron density and electron temperature rate decay in air are in good agreement with the published data. It was shown that despite the microns size of the laser plasma filament and electric field strength below the breakdown, we can achieve an exponential growth of the gas temperature, depending on the time delay between the initial femtosecond laser pulse and the laser guided filamentary spark discharge.
