Paper Abstract

The primary goal of the paper is the use of acoustic measurements to investigate the interaction of intense laser radiation with liquid in the dispersed state. It is well known that the formulation and solution of such problems involve optoacoustics, describing, in this case, acoustic waves generated in the liquid as a result of thermal or striction effects of laser radiation. In this investigation, we use acoustic measurements to determine either the absorption of the substance (optoacoustic spectroscopy) or the spatial radiation structure (optoacoustic tomography). Moreover, the authors have used acoustic measurements to obtain the thresholds of phase transitions in liquid aerosols. The latter result provides important information needed in experimental optical studies of aerosols.
