Burst pulse mode was employed to explore contaminant removal efficiency, while at the same time, assessing the degree of damage produced to the underlying original substrate surface. The surface morphology and composition of the deteriorated bone have been characterized, along with the effects of laser irradiation at 1064 nm, using Optical Microscopy (OM), Scanning Electron Microscopy-with Energy Dispersive X-ray Spectrometry (SEM-EDS), and X-ray Photoelectron Spectroscopy (XPS). The most effective laser cleaning parameters in burst mode have been identified in order to optimize the emission parameters of the laser, thus localizing its interaction within the outermost layers of contaminants and degradation products, avoiding damage to the underlying original bone surface. Hence, threshold cleaning and substrate damage values have been determined for this new sub-ns laser, paving the way to safer laser cleaning procedures that may be useful for the effective conservation of bone archaeological artifacts. 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/grantAgreement/ES/MICINN-AEI-FEDER/PGC2018-093925-B-C33 info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 0.342 2021 Chemical Engineering (miscellaneous) 2021 Q2 Engineering (miscellaneous) 2021 Q2 Physics and Astronomy (miscellaneous) 2021 Q2 Materials Science (miscellaneous) 2021 Q2 Environmental Science (miscellaneous) 2021 Q2 2.7 2021 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion de la Fuente, G.F.
