Double-pulse laser induced breakdown spectroscopy in orthogonal beam geometry to enhance line emission intensity from agricultural samples. Repositório Alice
NICOLODELLI, G.; SENESI, G. S.; RANULFI, A. C.; MARANGONI, B. S.; WATANABE, A.; BENITES, V. de M.; OLIVEIRA, P. P. A.; BOAS, P. R. V.; MILORI, D. M. B. P..
A soil, a plant and a fertilizer sample were investigated by double-pulse (DP) laser-induced breakdown spectroscopy (LIBS) in orthogonal beam geometry using a reheating configuration. The DP-LIBS signal enhancement was evaluated with respect to the corresponding single-pulse (SP) LIBS as a function of the interpulse delay at various ablation energies. The maximum signal enhancement measured was 155-fold when low ablation energy (4 mJ) and an interpulse delay of 10 μs were used. At high laser energies (≥16 mJ) and interpulse delay of 0.6 μs, the maximum signal enhancement was up to 3-fold. The effect of excitation energies and interpulse delays on emission line intensities was discussed in the various conditions used. The...
