Characterization of laser plasma by Cu, Cu/Be and Cu/Sn alloy targets

► The properties of plasma produced by laser ablation of pure and doped targets have been studied. ► The investigated targets were pure Cu, Cu with 2% of Be and Cu with 4% of Sn, in order to assess the influence of these admixture on the emission characteristics of plasma ions. ► The emission of Cu ions exhibited a higher gain from the Cu/Be and Cu/Sn plasmas with respect to the pure Cu one. ► We also performed studies of the temperature, ion velocity and charge angular distribution for the three plasmas.
