Gill, M and Perrie, W and Papworth, A and Fox, P and O'Neill, W (2005) Formation of nanoparticles from ultrafast laser condensates of metal targets. Proceedings of SPIE - The International Society for Optical Engineering, 5713. pp. 560-567. ISSN 0277-786XFull text not available from this repository.
Optimised ultrafast laser ablation can result in almost complete ionisation of the target material and the formation of a high velocity plasma jet. Collisions with the ambient gas behind the shock front cools the material resulting in the formation of mainly spherical, single crystal nanoscale particles in the condensate. This work characterises the nanoscale structures produced by the ultrafast laser interactions in He atmospheres at STP with Ni and Al. High resolution transmission electron microscopy was employed to study the microstructure of the condensates and to classify the production of particles forms as a function of the illumination conditions.
