Formation of the spectra of multiply charged ions from the plasma of Nd-doped glass irradiated with a neodymium laser

Abstract

The effect of neodymium ions on laser-induced glass destruction and the formation of the spectra of laser plasma ions is studied by the mass-spectrometric and optical-microscopy methods. As the Nd ion concentration increases, the degree of laser-induced damage in silicate glass increases, the threshold intensity for the glass destruction decreases, the maximum ion charge number Z _max and the maximum ion energy E _max decrease, and the energy spectra of target ions change. All this is related to both the coincidence between the lasing lines and the absorption bands of Nd ions and the intensifi cation of recombination processes in the multicomponent laser plasma.
