We are investigating the processes of shock-induced melt and laser-induced spallation. We are exploring these studies because they are relevant to defense and geological applications. Z-Beamlet (ZBL) produces a shock by laser ablation of the front surface of a planar target. The shock propagates through the sample toward the rear surface of the target. In addition to using ZBL as the shock driver, long pulse and short pulse optical probes view the rear side of the material. The long pulse probe is a line-VISAR (Velocity Interferometry System for Any Reflector) diagnostic and the short pulse probe is a 2D Reflectivity/Interferometry diagnostic.
