Abstract

Low pressure differential mobility analysis and transmission electron microscopy were used to study the aerosol formed during 1064-nm pulsed Nd3+:YAG laser ablation of a solid cesium iodide (CsI) target. Measurements reveal that the aerosol is comprised of particles in three size regimes: particles with approximately log-normal size distributions and Dpg ~ 10 nm, compact spherical CsI particles with Dpg ~ 80 nm, and fractal-like agglomerates with Dpg ~ 1-3 μm.
