Abstract
We have been developing HED experiments on high power ICF lasers over the past two decades that span (1) the radiative hydrodynamics of ICF capsule physics; (2) the high pressure, high strain rate, solid-state dynamics relevant to novel concepts for ICF and hypervelocity impacts in space and on Earth; and (3) the shock driven turbulence of exploding stars (supernovae). These different regimes are separated by many orders of magnitude in length, time, and temperature, yet there are common threads that run through all of these phenomena, such as the occurrence of hydrodynamic instabilities. Examples from each of these three seemingly very disparate regimes are given, and the common theme of hydrodynamic instability evolution is explored.

We describe experiments, starting in about 1990 on the Nova laser, transitioning to the Omega laser in 2000, and starting up on NIF in 2010, to study the Rayleigh-Taylor (RT) instability in ICF, solid-state plastic flow, and in astrophysics, in particular, supernova (SN) explosions
We show the RT growth factor vs. time for a 2-mode pattern corresponding to the superposition of 2 = 75 m and 3 = 50 m
