Abstract
A model is proposed for the ignition of a defect-density switching wav e in a crystal by powerful laser pulses. It is shown that the switchin g wave arises as a result of the nonlinear dependence of the activatio n energy of the defect-formation process on the strain field due to de fects. The conditions under which a switching wave arises and the prof ile, velocity, and propagation direction of the wave are discussed. (C ) 1998 American Institute of Physics. [S1063-7842(98)01208-2].
