Abstract

A quantum-kinetic theory is suggested for point-like destructions generation in clear transparent dielectrics. Direct absorption of phonons with an energy exceeding the binding energy of a neural adatom with lattice may become a cause for destruction. The theory contains one phenomenological parameter requiring experimental verification. Nonetheless, the estimates that have been carried out well correlate with the magnitudes of threshold fields observed in experiment. The theory is applicable for ultrashort laser pulses of femtosecond duration. Destruction caused by pico- and nanosecond pulses is construed in terms of the processes occurring on the front edge of a strong laser pulse, in the femtosecond range.
