Описание
LPP emissions from some metal oxide targets were studied with reference to corresponding metal targets of pure quality. Emissions in the visible region were used for the spectroscopic procedures of LPP characterization. Spectroscopic investigations were also done to study the behaviour of expanding LPP under the influence of a perpendicular magnetic field. Photo-ablated target materials generated an electrical signal, which served as a probe signal alternative to track the charge states in plasma and for the different diagnostic aspects. Possibilities for a Tomographic Imaging of LPP were studied using Pixel Method. Digital Holographic Interferometry (DHI) and Angular Spectrum Propagation (ASP) were used to retrieve the phase distribution in LPP. The phase maps were reduced to chord integrated densities and radial electron density profiles were mapped, by an Abel inversion method.
