Analysis of tungsten spectral-lines recorded from laser-target experiment

Abstract

The paper is devoted to an analysis of selected experimental results obtained from space- and time-resolved spectroscopic measurements, which were performed during the interaction of an intense laser-beam (0.7 J, 2 ns) with a tungsten (W) target placed under high-vacuum conditions. The spectroscopic measurements were carried out by means of a Mechelle® 900 optical-spectrometer, and for the first time some tungsten spectral lines (WI and WII) were recorded. The most important parameters of a tungsten plasma plume were estimated using the fitting procedure. The appearance of the tungsten ions was also confirmed by a series of corpuscular measurements
