Abstract:Both the melting and evaporating efficiencies of the preparation process for ultrafine.metallic particles by laser beam have been calculated using a physical model founded on an investigation of the energy interaction between a laser beam and the surfaces of Al, Cu and Mo samples. It shows that the above efficiencies of Al rank first, and those of Mo rank last. However those of Al and Mo increase faster than those of Cu with increasing laser beam pulse intensity.
Key words: laser beam irradiation efficiency Al Cu Mo
