| Popis: | The optical near fields in close vicinity to plasmonic nanoscale objects show a considerable enhancement of the electrical field and are localized to dimensions much less than the wavelength of light. The authors show that an ablation process caused by the near-field enhancement of femtosecond laser pulses pattern the substrate below gold nanotriangles is a way to image the near-field distribution with a resolution below 20 nm. The mechanism of ablation studied by pulsed x-ray scattering reveals the nonthermal nature of the process. |
