532-nm Photonic Doppler Velocimetry Open
Photonic Doppler Velocimetry (PDV) systems operating at wavelengths shorter than the classical telecom band are of interest for low-velocity measurements and for measuring smaller particles ejected from a material. As velocity resolution i…

Development of a Photonic Doppler Velocimetry Diagnostic Operating at 830 nm Open
Photonic Doppler Velocimetry, originally developed at 1550 nm, has become over the past decades a standard diagnostic for studying material response to dynamic loading or for studying clouds of ejecta. However, it is known that its velocit…

Momentum Transfer During Laser-Driven Cratering Experiments Open
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,…

Laser-Driven Cratering into Porous Graphite: Experimental Investigation on Ejecta Distribution Open
Introduction The sustainability of satellites is threatened by the growing number of space debris in low-Earth orbit [1]. Moreover, Earth is also at risk from the perpetual threat of collision with a celestial body. Understanding the behav…
