Abstract

The paper reports results of studying the geometry of craters formed by the action of laser pulses on solid-state targets of aluminum and lithium films at a power density on the target of (1–5) × 10¹⁰ W/cm² and variation of the number of pulses in the range of 1–150, as well as the results of ex situ layer-by-layer analysis of lithium films on quartz coatings carried out using the method laser induced breakdown spectroscopy to determine the thickness of the films.
