Abstract

Analysis of experimental studies of laser action on condensed absorbing media performed for a wide spectral range from 0.248-10.6 micrometers has revealed that the processes of starting plasma formation are identical in that they display an erosion character of the laser plasma origin and a weak dependence of the threshold of its formation on the laser radiation wavelength, which is due to the locally inhomogeneous character of laser vaporization and near-surface plasma formation.
