Incoherent third and second harmonics generation and fractal structure of silver island film

摘要

Incoherent: diffuse and depolarized,component of the enhanced third harmonic generation (THG)intensity is associated with the third-order hyper-Rayleigh scattering (HRS)in 2-D random ensemble of silver nanoparticles. A comprehensive analysis of the linear and nonlinear light scattering in combination with the results of atomic force microscopy revealed the fractal nature of the silver island films.
