In this article we describe a dual-pulse excimer-laser-based imaging system used in the determination of ejected material velocities resulting from the interaction of KrF laser radiation (λ = 248 nm, pulse width FWHM=17 ns, I≈1011 W/cm2) with 20-μm aluminum particles under vacuum (P = 10-5 Torr) conditions. Material velocities measured 200-400 ns after arrival of the incident pulse ranged from 450 to 1200 m/s.
