Abstract

Nanostructured metal surfaces were created by depositing a 30 nm layer of bulk gold onto a periodic fused silica transmission grating. By exciting this with a femtosecond laser beam, in air, results in terahertz radiation being produced. This emission is angle dependent. Furthermore, the emitted radiation has a third order power dependence ruling out the chi((2)) process, optical rectification.
