Abstract :
In this paper, the potential of femtosecond pulse lasers for the cleaning application of sensitive painted artworks are discussed. A comparative study on the ablation rate and threshold of femto- and nano-second laser pulses of typical varnishes (dammar, mastic. etc) and pigments (red and white lead, vermilion, ochres etc.) have been performed
