Abstract

Measurements of the effective third-order susceptibility χeff(3)(ω,ω,ω,ω) of a colloid consisting of silver nanoparticles (NPs) in liquid carbon disulfide (CS2) are reported for excitation at 532nm. Changes in χeff(3)(ω,ω,ω,ω) were controlled varying the NP filling factor f. Cancellation and sign reversal of the nonlinear (NL) index of refraction and the NL absorption coefficient of the colloid were observed owing to competing contributions from the NP and the CS2 molecules. The Reχeff(3)(ω,ω,ω,ω) and Imχeff(3)(ω,ω,ω,ω) change linearly when f assumes values from 0.4×105 to 4.0×105. An analysis of the results is provided using a generalized Maxwell Garnett model that allowed evaluation of the NL susceptibility of the NP.
