What is it about?
Ultrashort fs pulsed lasers were used to clean the surface of historical stained glass window samples, in order to demonstrate that they may avoid damage caused by heat accumulation, a typical problem when treating surfaces with lasers. Laser processing parameters were succesfully demonstrated to be safe for cleaning historical stained glass window surfaces.

Why is it important?
Cleaning historical stained glass windows from Cathedral and other historical monuments is very strenuous and a significant challenge. This works demonstrates that modern, compact ultrashort pulse lasers are useful tools to clean stained glass window surfaces satisfactorily, avoiding any type of damage.
Perspectives
This work opens the way to apply fs lasers to practical cleaning of Cultural Heritage stained glass windows in-situ and within an automated protocol.
