Ionization processes at the long laser pulses influence on a carbon aerosol. Part I
The interaction mechanisms of low-energy long duration (~ 1 ms) laser pulses with dispersed particles in air are considered. The basic equations describing the mechanisms of particle motion in a plasma flow, during heating, thermal emission, and evaporation are formulated. Particular cases of equations solving for the evaporation and thermoemission prevailing effects of electrons from the particles surface are considered. Data on gas temperature changes in the plasma upon the injection of particles with a low (~ 5 eV) and high (~ 11 eV) ionization potential are presented. Possible chemical reactions in a dispersed carbon environment are analyzed and its influence on the change of plasma formation energy is shown.
