Kinetics of particles of the liquid-drop phase of erosion jets in crossed laser beams

The kinetics of the liquid-drop phase of a lead erosion jet in crossed laser beams was studied. Neodymium laser radiation was used in the primary interaction and for additional evaporation. The diameter, and the number and volume concentration of particles in an erosion jet, were measured. It was possible to alter greatly the parameters of the condensed phase in crossed beams at low energies of the evaporating laser radiation. The results obtained should be useful in the generation of two-phase jets with controlled parameters and of a sterile drop-free erosion plasma.
