Выполнено сравнение объема парогазовой полости, образовавшейся в жидкости, и перепадов давления, возникающих в момент действия лазерного импульса и в фазе «коллапс-возобновление» парогазовой полости. Полученные результаты полезны для развития технологий лазерных эндохирургических вмешательств, требующих эффективного разрушения патологических биотканей, например, лазерной экстракции катаракты.</p></abstract><trans-abstract xml:lang="en"><p>The results of a study of hydroacoustic processes stimulated in a volume of distilled water by powerful microsecond pulses of Yb,Er:Glass laser radiation delivered through optical fibers with two different shapes of the output end are presented. A comparison of the volume of the steam-gas cavity formed in the liquid and the pressure drops that occur at the moment of the laser pulse action and in the “collapse-rebound” phase of the vapor-gas cavity is presented. The results obtained are useful for the development of technologies for laser endosurgical interventions that require effective destruction of pathological biological tissues, for example, laser cataract extraction.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>Yb</kwd><kwd>Er:Glass-лазер</kwd><kwd>микросекундные импульсы</kwd><kwd>парогазовая полость</kwd><kwd>форма выходного торца волокна</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Yb</kwd><kwd>Er:Glass laser</kwd><kwd>microsecond pulses</kwd><kwd>steam-gas cavity</kwd><kwd>shape of the fiber output end</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Куликова И.Л., Паштаев Н.П.
