Long Pulse Laser-Driven Shock-Induced Damage in Metals

Wesley Keller | 22-FS-003

Project Overview

This study investigated the viability of high-energy (>100 J/pulse), 100 ns width laser pulses forshock drive testing of metal targets. Radiation hydrodynamic simulations experimentally anchored to laser drive tests conducted at LLNL's Optical Science Laboratory (OSL) were used to evaluate laser energy coupling, shock drive, and damage accumulation across a range of test conditions.

Mission Impact

This study evaluated laser source requirements for a high-energy, long-pulse laser drive testbed in LLNL's Optical Science Laboratory (OSL).
