Abstract

We present here studies of laser imploded glass microballoons by the newly developed time-resolved four-frame X-ray shadowgraphy. The simulation results of our one-dimensional Lagrangian hydrodynamical computation code (WL code) are in good agreement with the diagnostic experiments. The joint effort of the diagnostic experiments and theoretical simulations is crucial to understand laser implosion dynamics.
