Paper Abstract

The mathematical model of the nonequilibrium heating and the phase transformations in Si is considered induced by the nanosecond pulse laser irradiation at 1.06 micrometer. Taken into account are the complex dynamics of the radiation absorption, the electron-hole plasma development, the heat diffusion and the radiation transfer. The simulation results show the self-regenerative nature of the radiation absorption process as well as significant overheating of plasma and formation of overheated metastable region in solid phase.
