Abstract
Time-averaged radiation spectra of laser-produced erosion tin plasma are obtained. The peculiarities of formation of excited states of tin atoms and ions in a laser torch at the 1 and 7 mm away from a target have been investigated. The radiation dynamics of the most intense spectral lines of atoms and ions has been analyzed. The correlation of radiation intensities in the maximum for atom and ion spectral lines, recombination times of single- and double-charged ions in a laser-produced tin plasma, and the velocity of plasma propagation have been estimated.
