Abstract

Emission spectroscopy studyworks permitted us to characterize plasma produced by a Q- switched neodymium-glass laser on a space and time scale (1.054 micrometers , 27 ns,), for incident power densities ranging between 2 10⁸ and 6 10⁹ W/cm², on solid targets (aluminum, graphite, SiC) under vacuum (ambient pressures of the order of 10^-3 Pa). For these experimental conditions the electronic temperature is a few eV and electronic density is around 10¹⁷ cm^-3.
