Holographic interferograms from laser fusion code simulations

The simulation of interferograms for laser fusion‐type targets is described. Three‐dimensional ray‐tracing postprocessors to the two‐dimensional hydrodynamic codes lasnex and sage are used for this purpose. Simulated interferograms can then be directly compared with experimentally obtained interferograms, thus providing insight into various aspects of target physics, such as anisotropic thermal transport and details of the hydrodynamic flow. The method is illustrated for two specific KMS microdisk target shots diagnosed with double‐exposure holographic interferometry.
