Abstract
The results of studying the spectra of optical breakdown plasma under two-pulse and single-pulse excitation in an ultrasound field are reported. It is shown that the efficiency of using ultrasound for recording the trace concentrations of chemical elements in a liquid under one-pulse excitation of the liquid is comparable to the efficiency under a two-pulse optical breakdown.
