Abstract
It is well known that the fume produced during pulsed laser ablation, for example during the structuring of ceramic micromolds, contains a significant nanoparticle component [1-6]. The relative concentration of nanoparticle emission is influenced by the laser parameters, including pulse duration and pulse overlap [7], and may rise to 99\% of the total particulate emission for shorter laser pulses [2]. Currently there are insufficient data on the parameters influencing the generation of nanoparticles during pulsed laser ablation and their characteristics; but it is clear that the release of these highly breathable particles constitutes a health risk.
