Ionicdielectric breakdown by laser radiation
Abstract
The breakdown of alkalihalide crystals by a laser monopulse is investigated which is caused by the development of an electron avalanche. An electronavalanche theory that takes the umklapp process into account is constructed on the assumption that the PO interaction of conduction electrons with lattice vibrations is dominant. The kinetic difference equation is solved for the range where the electron energy is less than the photon energy, and the diffusion equation in energy space is solved for the range where the electron energy is greater than the photon energy. Reasonable agreement between the theoretical results and experimental data is obtained in the case of alkalihalide crystal breakdown 1.06micron laser radiation.
