REMOVAL OF BIODETERIORATION FROM SURFACE OF STONE MONUMENTS BY MEANS OF LASER TREATMENT. СASE STUDIES OF CONSERVATION WORKS CARRIED OUT BY LASER

Results of conservation works on conservation of marble sculptural monuments, which have been carried out in St. Petersburg, by means of pulsed solid-state Nd:YAG laser with wavelength of 1064 nm are presented. It was shown that laser treatment allows one to remove from sculptures surface both biological films (incuding microfungi and lichens) and other typical deterioration layers.
