M. Strzelec,J. Marczak,A. Koss,R. Szambelane. Design and analysis work is now proceeding, with a view to selecting the baseline and entering the detailed design phase by early 2007, with construction starting by the end of 2009. In the following, we outline the design of OWL, its guiding principles, and summarize its strength and weaknesses.

Overpaint Removal on a Gilded Wooden Bas-Relief Using a Nd:YAG Laser at 1.064 μmbinding media. The painting layers cover only the parts of complexion and hairs of figures. The application of a 1.064 μm, Q-switched, Nd:YAG laser, allowed to unveil, in a short time the intact substrate of the object with well preserved gilding remains.

Anti-Fungal Laser Treatment of Paper: A Model Study with a Laser Wavelength of 532 nmwitched Nd:YAG laser operating at 532 nm and a pulse duration of 8 ns. Colour differences were determined spectrophotometrically. Best cleaning results were observed with fungi such as . and .. Dry laser cleaning generally turned out to be superb over wet bleaching approaches.

Chemistry of Parchment-Laser Interaction wavelengths (1064 nm), photochemical alterations are absent, solely thermally induced crosslinking of the collagen fibres is observed. Scanning electron microscopy proved only sensitive to phase changes like melting accompanying ablation above the threshold fluence.
