Laser Produced Radiative Blast Wave Hydrodynamics
Abstract
We report experiments on high power laser driven radiative blast waves. We focused 100J-1 kJ laser pulses onto pin targets immersed in background gases and observed the blast waves produced by the explosion of the laser heated pin. We then placed periodic obstructions of various wavelengths in the path of the wave and measured the damping rates of the resulting disturbance as a function of the wavelength of the obstruction. Our measurements will be compared to theoretical predictions of these rates based on the model of the pressure driven thin shell overstability (1), which is thought to play a major role in supernova remnant hydrodynamics. 1)Ryu, Dongsu and Vishniac, Ethan T.
