“…We proposed to replace the static effect with an acoustic effect [9], which looks quasi-static with respect to the rapid processes of plasma dispersion during optical breakdown. Important works were related to the study of the combined effects of laser radiation and ultrasound [9][10][11]. One of the important goals in this direction is to develop the fundamentals of combined laser and ultrasonic sensing of micro inhomogeneous liquids to increase the sensitivity of elemental composition spectroscopy with application to the study of the composition of various substances in seawater.…”

To conduct elemental analysis of seawater in situ, the method of ultrasonic spark spectroscopy was used, which was implemented as an automated complex for studying spectral optical characteristics and other hydrophysical characteristics of seawater. The complex was tested in expeditionary conditions during the voyage No. 81 of the R/V Professor Gagarinsky in the Sea of Japan in August 2022 and in the 52 voyage of the R/V Academician Boris Petrov in the Atlantic Ocean in October - December 2022. New data on the state of seawater with high spatial resolution have been obtained. The complex can be recommended for in-situ studies of the state of natural water areas.

“…The reason for this effect should presumably be sought in different conditions of the appearance of bubbles nucleus in a standing wave when exposed to ultrasound on a liquid during an optical breakdown. Descriptions of the results related to the dynamics of the lines of various elements during the development of laser breakdown in the ultrasound field are partially contained in [21][22][23]. The spectral data base (Atomic Spectra Database) was used everywhere when analyzing the results [24].…”

This paper develops the study of the effect of powerful ultrasound on the laser breakdown of liquids and a comparative study of the possibilities of acoustic and optical diagnostics of breakdown. The method of laser-induced breakdown spectroscopy (LIBS) for elemental analysis of liquids, along with high efficiency, continues to be less sensitive compared to traditional chemical methods. The paper develops a method of using additional ultrasound irradiation of the laser breakdown area in order to increase the efficiency of LIBS. Using the developed technique, spectral lines of chemical elements such as potassium, manganese, sodium, calcium, etc. were obtained for the first time depending on the frequency and power of ultrasound. It is shown that a sharp increase in the intensity of spectral lines of elements in water during laser breakdown is observed in the field of high-power ultrasound. It indicates an increase in the sensitivity of the combined method of ultrasonic LIBS. Along with the optical spectrum, the spectral and energy characteristics of acoustic emission were studied. An automated complex for hydrophysical and spectral studies is described, which was tested in the Sea of Japan during the voyage No. 81 of the research vessel RV "Professor Gagarinsky" in August 2022.
