Abstract

A comparison of the energetics and stoichiometry of effluents from YBa2CU307-x targets ablated by Nd:YAG (1064 nm) and excimer (248 nm) lasers is presented. NdrYAG ablative processes are characterized by specularly directed neutral atom/cluster formation with translational energies in the range of 2 - 20 eV. In sharp contrast, excimer ablation leads mainly to highly forward directed atomic ions with centroid energies between 200 and 400 eV. Analysis of the energetics indicates that different mechanisms are at play but both processes are non-equilibrium in nature.
