Abstract

We describe the configuration of two new optical diagnostics for laser-driven dynamic-compression experiments to multi-Mbar pressures. A streaked optical pyrometer (SOP) has been developed to provide temporally and spatially-resolved records of the thermal emission from shock-compressed samples. In addition, temporally-resolved broadband reflectivity is measured between 532 and similar to 850 nm by supercontinuum generation in an optical fiber. These new tools expand capabilities to probe the thermal and electronic states of matter at high pressures and temperatures using the Lawrence Liver-more National Laboratory's Janus laser.
