Abstract: | Results of theoretical and experimental investigations into the spectra of acoustic signals generated by high-power pulsed
laser radiation propagating in the atmosphere in the breakdown mode are given in the present paper. In Part I, results of
theoretical and experimental investigations into the spectra of acoustic signals from laser breakdown initiated on a single
solid aerosol particle and an ensemble of monodisperse particles depending on the particle material and sizes are presented.
In Part II, spectra of acoustic signals from laser sparks in the atmosphere are analyzed, and the special features of the
spectra of acoustic signals from individual plasma formations and discrete laser sparks are discussed.
