Abstract
Auto oscillating surface optical-discharge plasma was formed in a metal vapor under normal conditions by steady-state irradiation with a cw CO2 laser delivering radiation of moderate (2 - 4.5 MW/cm2) intensity. A strong screening of the metal surface, which caused even completely stop evaporation of the metal, was observed. The auto oscillations were also the reason of vibrational process in the metal pool. Influence of the phenomena on metal surface treatment was discussed.
