Abstract
Both scanning laser irradiation mode and the static mode can cause damage to the materials with different thresholds. In this paper, a simple criterion is derived theoretically to equate the threshold of static irradiation with the scanning one for flat-top laser so that the two damage threshold at different scanning velocity can be compared. The results of numerical simulations are in good agreement with the criterion, and the preliminary experiments verify the criterion.
