Emission form excited neutral Ag and Na atoms, present in the ablation plume, is detected with spectral and temporal resolution. The expansion velocity of Ag in the plume is estimated in ~1×104m s−1. Low-fluence laser ablation of the colloids yields ionized species that are analyzed by time-of-flight mass spectroscopy. Na+ and Agn+(n≤3) are observed. Composition of the mass spectra and widths of the mass peaks are found to be dependent on laser wavelength, suggesting that the dominant ablation mechanisms are different at the different wavelenghts.Financial support has been provided by Spanish DGI, MCyT (BQU2000-1163-CO2-01) and by the Ultraviolet Laser Facility operating at FORTHIESL under the EU contract HPRI-1999-CT-00074.Hindawi Publishing CorporationDirección General de Investigación Científica y Técnica, DGICT (España)Ministerio de Ciencia y Tecnología (España)European CommissionConsejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2022202220022022info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501Publisher's versioninfo:eu-repo/semantics/publishedVersionhttp://hdl.handle.net/10261/258286reponame:DIGITAL.CSIC.
