Time resolved shadowgraph images of silicon during laser ablation: Shockwaves and particle generation

Abstract

Time resolved shadowgraph images were recorded of shockwaves and particle ejection from silicon during laser ablation. Particle ejection and expansion were correlated to an internal shockwave resonating between the shockwave front and the target surface. The number of particles ablated increased with laser energy and was related to the crater volume. © 2007 IOP Publishing Ltd.
