Terahertz emission from gold nanorods irradiated by ultrashort laser pulses of different wavelengths
Electron photoemission and ponderomotive acceleration by surface enhanced optical fields is considered as a plausible mechanism of terahertz radiation from metallic nanostructures under ultrafast laser excitation. To verify this mechanism, we studied experimentally terahertz emission from an array o...
