Evolution of steam and gas plume generation on laser treating of metals in liquid

Evolution of steam and gas plume generation on the surface of an irradiated metal was investigated experimentally. It is shown that on using GOR-100M operating in a free oscillating regime the form of a crater developed in an irradiated target beingin water and air differs drastically.It is found that the substantial difference in the forms of crater surfaces developed is determined by different character of plasma, steam and gas mixture flow.
