The Energies and Pressures of Acoustic Transients Associated with Optical Cavitation in Water

Abstract The acoustic transients associated with optical cavitation in water have been studied using a high-speed interferometric technique. Radial pressure profiles of these spherical transients have been obtained over a range between 2 and 22 mm from the centre of the cavity. Pressure-radius relationships and transient energies have subsequently been determined for the acoustic waves and the volumes of liquid enclosed within them.
