Nanoparticle formation by the debris produced by femtosecond laser ablation of silicon in ambient air
Papers on ultra-fast laser ablation began to appear around 2004 and tended to concentrate on the material removal, depth and features of the ablation crater itself. This paper was one of the first to look at the nanoparticle debris adjacent to the crater. The purpose of this interdisciplinary study was to ascertain particle size using a little studied pulse length regime of 180fs. Knowledge of the particle size is an important characteristic of the process and its viability as a potential method for producing nanoparticles. Importantly the paper also reported oblate shaped nanoparticles, an unexpected result.
