Excimer Laser Ablation of Sodium Trisilicate Glass
Published online by Cambridge University Press: 25 February 2011
Abstract
We examine effects resulting from the irradiation of glassy sodium trisilicate (Na2O 3SiO2) with 248 nm excimer laser light at fluences from 1–5 J/cm2. We observe a threshold for the onset of etching of the surface at 3 J/cm2. We present SEM images of the resulting surface topography under etching conditions as well as recent measurements of the particle emission and photon emission from atoms leaving the surface region. A clear correlation is observed between this etching threshold and a) onset of emission of fast excited neutrals, as well as b) the appearance of atomic Na D resonance radiation emitted from particles up to several cm from the surface. We also present identifiction of the emitted positive ions.
