Abstract: Conditions of laser irradiation of a zinc target under which large droplets of a laser target material are not formed in the erosion plume are found, and zinc nanofilms with a minimum number of large particles on the surface are produced. The surface structure, thickness and optical characteristics of zinc films are determined as functions of the power density of laser radiation falling on a zinc target. The evaporation threshold for a zinc target irradiated by nanosecond laser pulses is found.

Keywords: laser-plasma deposition, nanosized zinc films, laser erosion plasma.
