Abstract

Nonlinear optical activity due to spatial dispersion is observed in a colloidal solution of silver. It is shown experimentally that the effect is substantially enhanced (by a factor of ∼102) when the silver particles aggregate into fractal clusters. The self-rotation angle of the plane of polarization is 2 mrad at an intensity of 2MW/cm2 for λ=0.532μm and a pulse duration of 11 ns. A method of separating the contributions of the local and nonlocal effects to the rotation of the plane of polarization is proposed and implemented.
