摘要
Emission of terahertz radiation is observed when semi-continuous ultrathin gold films near the percolation threshold are excited with femtosecond near-infrared laser pulses. Our experimental results suggest that the emission is through a percolation-enhanced second-order nonlinear optical rectification process.
