The results of a complex study of the ablation of metals when they are acted on by radiation pulses 40-300 ns wide from neodymium laser are presented. Low-thresholds surface ablation has been detected in a number of metals at surface temperatures below the boiling point, before the instant plasma formation, with a burst of particles of the condensed disperse phase and the formation of microstructures with a characteristics size of 1-10 micrometers . A description is given of the laser-induced ablation model, based on the purely thermal action of laser radiation and the natural inhomogeneity of solids.
