Momentum Transfer During Laser-Driven Cratering Experiments

Abstract The use of high power pulsed lasers to simulate hypervelocity impacts (HVI) was proposed several decades ago [1] and several studies were devoted to the analogy between laser-driven and real projectile cratering experiments. These studies, that were mostly focused on the crater size, suggest that laser-driven impact (LDI) is a promising tool to study the effect of very small (below 300μm) and very fast (above 30 km/s) projectiles [2]. This paper presents experimental results of laser-driven cratering experiments on aluminum and porous graphite, with a focus on momentum transfer. Analysis of this experimental data suggests that the contribution of the debris to the total momentum can be either small or significant depending on some laser parameters such as focal spot and pulse duration. Using the HVI-LDI analogy, these results suggest that the shape of the equivalent projectile has a major effect on the momentum enhancement factor. Numerical simulations are presented, and are consistent with this observation.

Abstract

This paper presents experimental results of laser-driven cratering experiments on aluminum and porous graphite, with a focus on momentum transfer. Analysis of this experimental data suggests that the contribution of the debris to the total momentum can be either small or significant depending on some laser parameters such as focal spot and pulse duration. Using the HVI-LDI analogy, these results suggest that the shape of the equivalent projectile has a major effect on the momentum enhancement factor.
