Since 1995, while Costas Fotakis first introduced jointly restorers and scientists to debate the opportunity of lasers in paintings conservation, the sector has grown significantly in value, and this day restorers and laser scientists interact to advance new functions. This ebook provides the greater than six dozen study papers ready for LACONA V (Lasers in paintings Conservation), held in Osnabrueck/Germany in September 2003. The 5th congress once more gathers restorers, paintings historians, museum employees, laser scientists and laser brands. the themes comprise, between others: laser cleansing of works of art (case stories and facet effects), removing of former conservation layers, basics of laser-artwork interplay, on-line tracking and technique keep an eye on, laser diagnostics, spectroscopy for tracking and identity, networks and co-operation projects.

Laser treatment seems to be most successful in cases where the material to be removed is located on the surface or has penetrated only slightly between the ﬁbres. On basis of the laser cleaning trials, it can be concluded that the green laser (532 nm) has the highest cleaning eﬃciency and the least (visual and chemical) side eﬀects for the removal of inks, stamps and surface dirt from originals. The UV laser (248 nm) has proven to be the most eﬀective tool in the removal of homogenous layers of adhesive from original objects .
An artiﬁcial aging resulted in neglectable changes in lightness and yellowness of the laser cleaned laboratory soiled samples but inﬂuenced the changes in non soiled samples. Marked changes were noticed due to 266 nm, 355 nm and 1064 nm irradiation and were ascribed to the photochemical damage of the cellulose ﬁbres and to enhanced absorption of the laser radiation by the soil particles. 1 Introduction The cleaning and conservation of historical documents on paper represent a diﬃcult task for restorers due to the delicate substrate material.
The results above shows, that ultraviolet radiation accelerates the aging process in cellulose. Samples of paper artiﬁcially soiled with the charcoal powder dust were eﬀectively cleaned at all laser wavelengths applied. In the case of the 1064 nm radiation the largest surface yellowing was measured compared to 266 nm, 355 nm and 532 nm. This was ascribed to the thermal component prevailing in processes due to material ablation induced at the longest wavelength applied. For samples produced contemporarily with the gelatine glue additive the increased yellowing of the paper surface after laser cleaning with 266 nm and 355 nm was revealed, for the sample of since this additive increased the range of absorption of the paper.
