摘要：

Laser material removal applied to selective overpaintings and subsequent painting layers detachment was studied in order to select the best cleaning practice of painted artworks. The ablation depth as a function of incident laser fluence/intensity and irradiation pulse number was considered as a reference parameter. We have measured the ablation depth with both a contact microprofilometer and a white light interferometer as a function of laser irradiation parameters. The measurements have evidenced that the ablation depth in our experiments varied between 2 and 100 mu m making possible selective removal of painting.
