海报摘要

Laser cleaning techniques could be considered amongst the most noteworthy contributions of Physics toward the conservation of artworks. Although having established themselves as a striking field of research for the last three decades, these techniques have attracted limited attention from the archaeological conservation community. Laser-assisted removal of contamination and deterioration products in archaeological bones and flints is a subject of great interest to improve recovery and conservation. This research work reports on studies aimed to evaluate the application of two different ultrashort pulsed lasers for the elimination of contaminants on significant Pleistocene bone and Neogene flint surfaces in an attempt to safeguard their archaeological value and origin. The results indicate that fs UV laser irradiation is significantly safer and more efficient at cleaning than sub-nanosecond laser irradiation, owing to the controllability of laser irradiation parameters, which allow for a systematic and accurate parameter description of an actual laser cleaning intervention.
