   <abstract xml:lang="ru">
    <p>Рассматривается механизм инактивации планктонных микроорганизмов ударными акустическими волнами. Ударные волны возникают при очень быстром образовании и схлопывании пузырьков пара в жидкости, локально нагретой до температуры, превышающей порог кипения. Локальный нагрев осуществлялся импульсным лазерным излучением с помощью органических фототермических сенсибилизаторов. Эффективный фототермический сенсибилизатор должен иметь очень короткое время жизни (пикосекунды) возбужденных состояний. Таким условиям удовлетворяют высоковозбужденные электронные состояния (ВВЭС) органических красителей. ВВЭС красителей заселялись путем ступенчатого поглощения молекулой двух квантов падающего излучения через нижние возбужденные уровни. Возникновение и исчезновение пузырьков пара исследовано по кинетике светорассеяния низкоинтенсивного зондирующего луча гелий-неонового лазера.</p>

    <p>Mechanism of inactivation of plankton microorganisms by acoustic shock waves is discussed. Shock waves occur at very rapid formation and collapse of vapor bubbles in a liquid locally point heated to a temperature exceeding the boiling. Local heating was provided by pulsed laser excitation of organic photothermal sensitizers. An effective photothermal sensitizer should have a very short lifetime (picoseconds) of excited states. High excited electronic states (HEES) of organic dyes follow this requirement. HEES are produced as a result the stepwise absorption of two photons by the molecule through the lower excited states. The formation and disappearance of vapor bubbles in the solution was detected as a change in the light scattering of a low-intensity helium-neon laser beam passing through the cuvette.</p>
