Plasmon-Enhanced Sub-Wavelength Laser Ablation: Plasmonic Nanojets

Authors


Abstract

original image

In response to the incident light's electric field, the electron density oscillates in the plasmonic hotspots producing an electric current. Associated Ohmic losses raise the temperature of the material within the plasmonic hotspot above the melting point. A nanojet and nanosphere ejection can then be observed precisely from the plasmonic hotspots.
