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


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.
