Abstract
During the last decade, laser ablation process has been just utilized for removal of encrustation at works of art and architectural historical objects. This technique utilizes substantial difference in laser radiation absorption coefficients of encrustation and substrate. In the paper authors present next architectural object cleaned with pulse laser radiation - limestone epitaph and stalls of King Batory's Chapel at Wawel Castle in Cracow, Poland. Experimental results include measurements and optimization of laser fluency in dependence on radiation wavelength of Nd:YAG laser with harmonic generation as well as colorimetric (hue) measurements of objects before, during and after laser cleaning.
