Paper Abstract

The theory of defect-strain instability with formation of periodic surface relief in semiconductors irradiated by ultrashort ((tau) p equals 10-13 s) laser pulse is developed. The period and time of formation of surface relief are calculated. Regimes of multipulse laser ablation leading to formation of either smooth surface or arrays of surface relief spikes are considered and corresponding experimental results are interpreted from the viewpoint of the developed theory.
