Hydrodynamic Efficiency Measurements in Laser-Imploded Targets
Abstract
We have found that numerical simulation and experiment both show laser-imploded spherical glass shells to expand in two successive pulses: The first corresponds to the ablated material, while the second corresponds to the compressed material. The relative speeds and intensities of the two pulses indicate the efficiency of transferring absorbed laser energy to the compressed core.
