Paper Abstract

The effect of the formation of large-scale structures on a target surface is experimentally and theoretically studied. The conditions of structures growth as a function of the background gas pressure, laser radiation intensity, and its angle of incidence are defined. A mechanism of structure generation associated with the instability of capillary waves in the field of the laser torch pressure is proposed. A dispersion equation describing instability is obtained, whose analysis gives noncontradictory explanation of the experimental results.
