Paper Abstract

Experimental investigation results of plasma characteristics formed on a solid-state obstacle surface during ambient optical breakdown under the influence of a powerful pulse CO2 laser are given. The results touch upon the problem of three aspects: a front motion velocity of formed plasma radiation interaction. The effect of energy density (or average power) in an irradiation spot, an obstacle material, and a laser pulse shape (length) on the process characteristics is an order of 10 cm2 that makes it possible to neglect two-dimensional effects.
