Paper Abstract

The optical properties of deposition zones formed by an erosion plamsa torch diverging in a vacuum, arising as a result of the action of a high-intensity, unpolarized laser radiation on a copper target are investigated. A very interesting effect has been revealed. On the substrate, approximately at the center of the deposition zone, coaxially to the laser beam, a ring with clearly defined boundaries was detected. The density of the deposited material in this ring was much smaller than in other places. An analysis of the state of the substrate in the ring has shown that this region is formed as a result of the effect of ionic clearing of the surface.
