Dynamics of formation of the liquid-drop phase of laser erosion jets near the surfaces of metal targets

Diagnostics of a Crater Growth and Plasma Jet Evolution on Laser Pulse Materials Processing

“…At a radiation flux density 10 6 -10 7 W A B cm 2 the bulk evaporation is typical of all metals used in the experiments [5]. Obviously, the presence of the external electric field affects (increases or decreases depending on the direction of the field strength vector) the velocity of motion of the plasma front and causes some distortion of the plasma cloud shape.…”

“…The metal is melted and evaporated. As a result of local formation of steam and plasma [4,5], the erosion torch begins to form with the fine-dispersed liquid-droplets phase.…”
