Frequency and temperature dependences of avalanche ionization in solids under the influence of an electromagnetic field

Formulas for the critical field are obtained on the basis of a solution of the kinetic equation. It is shown that its dependence on the temperature is determined essentially by the ratio of the frequencies of the field and of the electron-phonon collisions. This makes it possible to evaluate experimentally the role of the electron avalanche as a laser-damage mechanism.
