Ashiqur author Fuente Leis, Germán F. de la author Carretero Díaz, José Miguel author Alonso Abad, Mª Pilar author Navazo Ruiz, Marta author Alonso Alcalde, Rodrigo author Chapoulie, Rémy author Schiavon, Nick author Angurel Lámban, Luis Alberto author 2023-05 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. 0167-577X http://hdl.handle.net/10259/7872 10.1016/j.matlet.2023.134028 Femtosecond UV laser Laser cleaning Flint Sierra de Atapuerca Ultrashort pulsed Femtosecond UV laser for selective cleaning of significant Cretaceous flints
