Abstract
We present experimental observations of diffusely scattered second-harmonic light from a silver surface with weak random roughness. The roughness provides coupling of the incident wave to counterpropagating surface plasmon polaritons in the second harmonic. Rather than observing enhancement in the backscattering direction, a distinct minimum in the angular distribution is seen.Keywords
