LASER CLEANING OF HISTORICAL MONUMENTS
Read the full article
Results of experimental work on laser cleaning of historical copper monuments are presented. Surface cleaning was carried out by means of pulsed Nd:YAG laser (wave length of 1064 nm, pulse duration of 30-110 μs, energy density10-25 J/cm²). Efficiency of laser treatment was controlled using X-ray fluorescence spectrometer. Performed investigations demonstrated a high efficiency of laser cleaning and possibility of laser use with specified parameters in restoration of copper monuments.
