Ashiqur Ultrashort pulsed Femtosecond UV laser for selective cleaning of significant Cretaceous flints 2023 Access copy available to the general public Unrestricted This work reports on studies aimed to evaluate the utilization of ultrashort 238 fs (fs) pulsed UV laser emission at 343 nm for eliminating colored crusts and surface deposits on significant Cretaceous flint surfaces, in an attempt to safeguard its aesthetic appearance and archaeological value. The results indicate that fs UV lasers may be an ideal, non-contact tool for selective surface cleaning of sensitive archaeological artefacts, since they enable contaminant desorption while avoiding photothermal damage. info:eu-repo/grantAgreement/ES/DGA/T54-20R info:eu-repo/grantAgreement/EC/H2020/766311/EU/European Doctorate in ARchaeological and Cultural Heritage MATerials science/ED-ARCHMAT This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 766311-ED-ARCHMAT info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 2.7 2023 PHYSICS, APPLIED 76 / 179 = 0.425 2023 Q2 T2 MATERIALS SCIENCE, MULTIDISCIPLINARY 239 / 439 = 0.544 2023 Q3 T2 0.602 2023 Condensed Matter Physics 2023 Q2 Mechanics of Materials 2023 Q2 Mechanical Engineering 2023 Q2 Materials Science (miscellaneous) 2023 Q2 5.6 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Fuente Leis, Germán Francisco de la (orcid)0000-0002-0500-1745 Carretero, José Miguel Alonso Abad, Mª Pilar Ruiz Navazo, Marta Alonso Alcalde, Rodrigo Chapoulie, Rémy Schiavon, Nick Angurel, Luis A.
