What is Raman Analysis of Paper Ablation Products about?

Raman microspectroscopy was used to analyze the ablation products from laser cleaning of old paper samples. Pulsed laser radiation at 532 nm was used to ablate the paper, removing approximately 10% of the total paper thickness. Raman spectra identified cellulose fibers, fillers like calcite and titanium dioxide, proteins, and highly fluorescent species in the ablation products. A statistical analysis found proteins and fluorescent species were the dominant components removed. This ablation of fluorescent ma
