Abstract

The dependency of ablation rate and wavelength is studied by means of an exemplary chosen sort of sandstone in order to determine the cleaning regime and the feasibility of different wavelengths for practical cleaning. Excimer laser radiation (KrF, XeCl) and Nd:YAG laser radiation are used for the ablation of the black crust and sandstone in two independent experiments with a constant number of pulses. The Nd:YAG wavelengths at 355 and 1064 nm show advantages in cleaning this particular type of sandstone. A slight color change of the cleaned sandstone is detected in the case of cleaning at 1064 nm.
