Abstract
The ablation of cobalt with 20 ns pulses of 308 nm XeCl excimer laser radia tion is investigated. The dependence of the ablation rate on laser fluence, spot area, and pulse number is determined. The experimental results are co mpared with a numerical calculation based on an improved thermal model. The model, which considers proper vapor attenuation, is shown to be in good ag reement with experiment. (C) 2001 Elsevier Science B.V. All rights reserved .
