Disruption of charge equilibrium as a root cause of intrinsic optical breakdown in dielectrics

摘要

Within the framework of a previously proposed model, this work analyzes the processes in the lattice of a solid body that lead to an irreversible violation of charge equilibrium under the influence of an external electric field. A simple interpretation of the causes of the irreversible breakdown of bonds in the crystal lattice due to the charge motion inside the dielectric is provided, and the pathways and conditions for lattice instability under the influence of intense laser pulses are discussed.
