Abstract

Laser-induced plasma (LIP) was generated on the surface of an aqueous solution using a single pulse of the fundamental and second harmonic from a Q-switched Nd: YAG laser. Aqueous Ca, K, Mg, Na and Sr solutions were used to observe the presence of these elements in the plasma through the emission of their atomic species. In order to obtain the spectra of the aqueous solutions, we used a charge-coupled camera (CCD) in combination with a compact spectrometer. We also determined laser-induced plasma temperatures at 1064 and 532 nm with Boltzmann plots of hydrogen lines (656.28, 486.13 and 434.05 nm).
