Characterization of laser-induced plasma plume: Comparison between Al and Al2O3 targets

Characterization of the plasma plume produced by laser ablation from Al and Al2O3 targets was carried out on the basis of the line profile analysis of Al(I) (P--S) emission. The spatial distribution and density parameters of electrons and Al atoms in the plume were obtained by comparing observed spe...

Summary:Characterization of the plasma plume produced by laser ablation from Al and Al2O3 targets was carried out on the basis of the line profile analysis of Al(I) (P--S) emission. The spatial distribution and density parameters of electrons and Al atoms in the plume were obtained by comparing observed spectral line profiles with a theoretical calculation. The results showed different behavior for the Al and Al2O3 targets. The Al atoms from the Al2O3 target were populated in a smaller region than those from the Al target.
