Particle formation and size distributions of ablated particles were measured using an optical aerosol spectrometer. The structure of laser generated particles was studied by scanning electron microscopy. The results proved the relationship between particle formation and sample composition. Spherical particles in the diameter range of 0.25–2 µm and µm-sized agglomerates composed of primary nano-particles were observed.
