Ultrafast laser ablation for restoration of heritage objects

Rode, Andrei V; Baldwin, Kenneth; Wain, A; Madsen, Nathan; Freeman, Darren; Delaporte, Philippe; Luther-Davies, Barry

Description

Powerful ultrafast laser pulses have a unique capability to ablate material from the surface without heat propagation into the bulk due to the non-linear nature of the laser-surface interaction. This quality offers a new application of ultrafast lasers for restoration of objects of art and heritage artefacts. We discuss the laser-based cleaning methods used in art restoration, analyse the potential advantages and challenges of using ultrafast laser pulses, and present new encouraging results on...[Show more]
