Abstract: It is established that the action of ultrasound leads to both sharp enhancement of the acoustic emission and increase in the intensity of spectral lines of laser-excited elements dissolved in aqueous salt solutions (NaCl, NaHCO$_{3}$, CaCl$_{2}$), which provides a new method of combined laser–ultrasonic spark spectroscopy. The task of synchronization of the acoustic and optical emission has been solved, which reveals dependence of the intensity of spectral lines on the phase of ultrasonic wave action.
