Abstract
We study a new method for producing ultra-fine particles (nanoparticles) that employs pulsed-laser ablation of microparticles (LAM). Pulsed Nd:YAG laser radiation, 10-ns pulses at 1064 nm, was used to ablate 20-μm glass microspheres; and pulsed excimer laser radiation, 15-ns pulses at 248 nm, was used to ablate ~2-μm feedstock of silver, gold, and permalloy (Ni81%:Fe19%) under both normal atmospheric conditions and other ambients.
