Mathematical model of optical breakdown in gases

The mathematical model for calculation of the interaction processes of the laser radiation with optical break down plasma in gases is considered. The model is based on equations of onedimensional two-temperature hydrodynamics accounting for the thermoconductivity, radiation transfer and ionization and dissociation kinetics. The technique for approximate calculation of the volume effect for the plane one-dimensional task is proposed. The method for ionization kinetics and energy transfer equations common solution is described.
