Silicated micrometeorites (mass : 1/10 μg) impacting aluminium target are simulated with a neodyme pulsed laser, producing a maximum laser pulse energy of 100 in a few ns. The simulated micrometeorites velocities are in the range of 5 km/s-45 km/s; the mass loss ratio, Km, is related to particle velocity Vp by Km = 1.17 V1.52 p.Le laser au néodyme du GRECO I.L.M. délivrant des impulsions de l'ordre de 100 J en quelques ns, nous a permis de simuler des impacts de micrométéorites silicatées de quelques dixièmes de μg, de vitesse comprise entre 5 et 45 km/s, sur une cible d'aluminium. Les cratères produits dans la cible sont hémisphériques, et le rapport Km, de la masse éjectée sur la masse de la particule incidente simulée, varie avec la vite...
