Abstract

KrF excimer laser ablation of two artificially aged triterpenoid films was studied. Ablation rate variations across film thicknesses implied compositional change with depth. Deviations between calculated and measured depths-steps at deeper ablated layers verified previously determined gradients. The findings were confirmed with DTMS, which demonstrated that excimer laser ablation with optimum fluences does not induce oxidation.
