Paper Abstract

Numerical studies of the interaction of KrF laser pulses with pulselengths ranging from 10 fs to 15 ns with aluminum have been carried out at intensities around the threshold for damage. These results are compared with experimental measurements of interactions with pulse lengths of picosecond to nanosecond duration. The calculated damage thresholds and ablation depths agree reasonably well with those from experiments. For a material irradiated by femtosecond and picosecond pulses the damage threshold is sensitive to the material's electron-phonon coupling constant. The value of electron-phonon coupling constant which gives good agreement is close to that calculated based on free electron theory.
