Action of a rectangular pulse of a neodymium laser on porous metal targets

  • 15 Accesses

Abstract

By the method of laser probing the erosion products of porous metal targets of Al and W under the action of a rectangular radiation pulse of a neodymium laser are investigated. The diameters of metal particles in the erosion flame measured using an electron microscope and using laser probing are fairly close, which indicates the reliability of control of particle sizes in real time by the laser probing method. The possibility of decreasing the particle sizes by reevaporating them is shown.
