Abstract
Optical breakdown spectra on seawater and distilled water faces excited by Ti-sapphire laser pulses with durations of 50 fs and 650 fs were studied experimentally in normal atmosphere. The time dependence of the intensity of the Na I (588.9 nm) and Mg II (279.5 nm) emission lines was studied, and the limit of detection of Na in an aqueous NaCl solution was established at 10−6 g/l.
