LASER-INDUCED EVAPORATION OF METAL FILMS

Nanofi lms of zinc, aluminum, lead, silver, and copper have been obtained by the laser-plasma method. The conditions of deposition of such fi lms 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 infl uences the surface relief of the metal nanofi lms 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.
