Popis: | 2 Acerinox, S.A., Palmones, Los Barrios, E-11379 CSpain A pulsed Nd:YAG laser operating on the second harmonic wavelength at 532 nm was used in this work. The influence of sample surface topography on spectral emission of laser-produced plasmas was investigated. Stainless-steel samples with different grades of surface polishing (range 0.026-4.54 mm) were prepared and analysed using LIBS. The effect of surface roughness on analytical precision was found to be dependent on laser beam energy, with optimum results for beam irradiances in the range 28-57 GW cm 2 . The |
