Materials processing using high power pulsed lasers involves complex phenomena i ing rapid heating, superheating of the laser-melted material, rapid nucleation, and p explosion. With a heating rate on the order of 10 9 K/s or higher, the surface layer melte by laser irradiation can reach a temperature higher than the normal boiling point. On other hand, the vapor pressure does not build up as fast and thus falls below the sa tion pressure at the surface temperature, resulting in a superheated… CONTINUE READING
