Abstract

V originále

Scan analysis by Laser-Induced Breakdown Spectroscopy (LIBS) is usually performed as sampling in the series of single points (ablation craters), in one, two or even three directions. The spatial (lateral and depth) resolution is than determined basically by the size, depth and spacing of the ablation craters. Tightly-focused short-wavelength laser pulses enable production of both, small in diameter and depth ablation craters. However, for the smallest LIBS ablation craters the emission intensities mainly in single-pulse configuration are usually low, and not sufficient especially for minor and trace elements detection. Double-pulsed LIBS technique may significantly enhance the signal even if small amount of material per pulse is ablated. Therefore double-pulse LIBS instrumentation equipped with UV ablation laser and IR laser in reheating mode seems to be suitable system for achieving low detection limits with high spatial-resolution. LIBS ablation chambers enable further improvement of figure of merit using atmosphere of noble gases.
