Abstract

Based on measurements made by the intracavity laser spectroscopy method, quantitative diagnostics of laser erosion plasma has been performed at stages of low-threshold near-surface optical breakdown and afterglow: dynamic fields of densities of target material atoms and ions (Al and Ti) have been constructed (1011 - 1016 cm-3), electron density has been measured (approximately equals 1018 cm-3), and plasma temperature has been determined (approximately equals 25 kK).
