ACTION OF HIGH-ENERGY NEODYMIUM LASER RADIATION PULSES HAVING A DIFFERENT SPACE-TIME SHAPE ON METALS
V. K. Goncharov UDC 621.373.826:533.9 The role of different factors favorable for the arrival of the liquid-drop phase of the target material at the erosion flame has been elucidated. The crushing of particles of the liquid-drop phase in the process of their motion toward the laser beam has been revealed. The conditions under which the liquid-drop phase influences a laser-radiation loss have been determined. The methods of control of the parameters of the liquid-drop phase in erosion plasma flames have been found. A. N.
