About the generation of electric discharge in dielectric by photon flux

The development of an electric discharge during photon scattering in a dielectric material is considered. A preliminary mathematical model of the discharge process is presented. The model is based on a quantum kinetic equation for quasi-free charge carriers produced by bulk radiation effects and impact ionization. Equations are obtained for the concentration, drift current density, and gas temperature of quasi-free electrons. A test example is considered, confirming that the model does not contradict the known conditions for the formation of an electric discharge.
