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
