Abstract

The efficiencies of Nd:YAG and CO2 lasers at cleaning carboniferous and blonde sandstone were investigated by examining the effects of the translation velocity and the laser characteristics. 30 ns.1 In the present case, however, a CW, CO2 laser and a Nd:YAG laser, capable of generating pulse lengths of up to 20 ms, were used to investigate laser surface cleaning.
