Aluminium laser plasma, Intensity of radiation, Spatial characteristics,Abstract
The results of the studies on the intensity of luminescence of different spatial areas of the laser plasma of Аl are presented at different distances from the target. The intensity of the laser radiation was (4,4 − 4,8) ´ 108 W/сm2 at the gas pressures in a vacuum chamber at (6,7 − 133,3)Pa. The process of the shock waves formation is reflected on the dependence of the intensity of radiation of the laser plasma on the distance to the target at different pressures in a vacuum chamber as heterogeneities. The change of the pressure substantially influences such parameters of the laser plasma, as the size of the plasma plume and the concentrations of the particles in the plume.
