(a) Proposed femtosecond-laser-induced fragmentation process. (b) Electron temperature temporal evolution (dashed red curve); lattice temperature (solid black curve); and maximum water temperature at the NP surface-water interface (dash-dot blue curve), for a 60 nm diameter gold nanosphere and a single 400 nm laser pulse of 150 fs and fluence of 12.3 mJ/cm2. (c) TEM images representing reshaping and size reduction at low and high fluences for a 60 nm quasi-sphere. Reproduced with permission from ref (40). Copyright 2011 American Chemical Society.
