Plasmonics: Plasmon-Enhanced Sub-Wavelength Laser Ablation: Plasmonic Nanojets (Adv. Mater. 10/2012)

When a droplet hits the surface of water, it is often observed that a water column, or ‘back-jet’, surges upwards. Counterintuitive though it might be, a similar phenomenon can occur when ultrafast light pulses shine on a nanostructured metal surface. These sub-wavelength ‘nanojets’ occur in the regions of highest local field enhancements. For more details, see the article by V. K. Valev et al. on page OP29.
