Abstract

Preliminary experimental results are reported on the temporal characteristics of laser spark emission spectra. Sparks were generated in water by the focussed beam of a Q-switched NdYAG laser. Na and Cu aqueous solutions exhibited fluorescence signal on the decaying edge of the plasma emission at their respective characteristic resonance lines. Potential of laser plasma spectroscopy for in-situ pollution monitoring in natural and waste water is briefly discussed 1 Introduction This work was motivated by the world-wide increasing interest for new analytical methods applicable for in-situ monitoring of environmental pollution. Compared to conventional analytical methods, the laser in
