Microimplosions: Cavitation Collapse and Shock Wave Emission on a Nanosecond Time Scale

Phys. Rev. Lett. 84, 1328 – Published 7 February 2000

A streak camera with high spatial and temporal resolution was used for imaging the dynamics of the violent collapse in single-bubble sonoluminescence. The high pressure in the last phase of the bubble collapse leads to the emission of a shock wave, which is launched with a shock velocity of almost 4000 m/s. The shock amplitude decays much faster than 1/r. From the strongly nonlinear propagation the pressure in the vicinity of the bubble can be calculated to be in the range of 40–60 kbar.
