Laser-Induced Evaporation of Metal Films

Nanofilms of zinc, aluminum, lead, silver, and copper have been obtained by the laser-plasma method. The conditions of deposition of such films on substrates, providing the absence of metal particles on their surface, were determined. The threshold power densities of the laser radiation acting on a metal target, at which an intense evaporation of its material begins, were found experimentally. It is shown that the boiling temperature of the material of a target influences the surface relief of the metal nanofilms obtained. The conditions of obtaining fi lm coatings with small particles of the target material on their surface, which can be used for the realization of the giant Raman scattering, were determined.
