Shock wave interaction with laser-generated single bubbles

Phys Rev Lett. 2005 Jul 15;95(3):034501. doi: 10.1103/PhysRevLett.95.034501. Epub 2005 Jul 11.

Abstract

The interaction of a lithotripter shock wave (LSW) with laser-generated single vapor bubbles in water is investigated using high-speed photography and pressure measurement via a fiber-optic probe hydrophone. The interaction leads to nonspherical collapse of the bubble with secondary shock wave emission and microjet formation along the LSW propagation direction. The maximum pressure amplification is produced during the collapse phase of the bubble oscillation when the compressive pulse duration of the LSW matches with the forced collapse time of the bubble.
