Resum

Laser based analysis of artworks benefits from the development of hybrid instruments where a single laser source serves to excite fluorescence, Raman and laser induced breakdown spectroscopy (LIBS) signals. Laser induced fluorescence (LIF) and Raman spectra provide information at the molecular level, while LIBS serves for identifying the elemental composition of the substrate under consideration. Studies using several excitation wavelengths on different types of materials and substrates help to develop and establish these hybrid systems for the conservation of artworks.
