The last 20 years have seen a rapid increase in the use of lasers for the cleaning of artworks. Lasers have become a well-established tool in conservation and more and more art conservation groups work with lasers on an everyday basis. While the Q-switch Nd:YAG laser has become a most popular tool in this area offering an effective beam for laser cleaning at a relatively affordable cost, many conservators have become more concerned about the damage that the laser beam may impart into the surface of the material being cleaned and thus it has become important to assess the damage threshold for each material as a function of laser variables such as wavelength, angle of incidence and dose. Case studies have addressed fundamental questions about the interaction of the laser beam with a variety of materials.
