Seminar Energy density, temperature, and pressure upon spherical cavitation bubble collapse compared to femtosecond and nanosecond optical breakdown
Alfred Vogel

Details:

Optical breakdown and spherical cavitation bubble collapse are different nonlinear mechanisms producing a large energy density within a small spatial region. Extreme states of matter with pressures up to 107 MPa for femtosecond optical breakdown, and temperatures up to 108 K for the collapse of bubbles oscillating in a sound field have been claimed [1,2]. Direct experimental verification of such claims is impossible because of the small spatial and temporal scale on which the extremes occur. Instead, p and T have to be inferred from other experimental information and equation of state (EOS) data.
