Abstract
We report on measurements of the laser-driven electron emission from a granular gold film. The light source was a picosecond Nd:YAG laser. W e illuminated the sample using the harmonics of this laser fundamental frequency (wavelengths 532, 355 and 266 nm). By comparison with a smo oth gold thin film, the emitted current is three orders of magnitude h igher for the granular gold film at 532 nm. This enhancement is due to plasmon resonances in the gold particles. We discuss the possibility of using such a granular gold film as an electron source in a photoinj ector.
