Abstract :
We use a tightly focused ultrashort laser pulse to produce a third harmonic signal from an air-dielectric interface containing gold nanorods. When the fundamental frequency is resonant with the longitudinal plasmon of the nanorods, the third harmonic signal can be enhanced by more than 3 orders of magnitude.
