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.

Linear diffuse scattering for p polarization and λ = 543 nm. The backscattering direction (θs = −θi) is denoted by the dashed vertical lines; horizontal lines denote the outward coupling regions of single scatter (dashed horizontal lines) and the outward roughness coupling of ksp(ω) (solid lines). The detector slit width is 0.8°.
