Abstract

A scheme for measuring χ(3) using single-beam nearly degenerate forward four-wave mixing, which has the advantage of sensitivity and simplicity over some previous methods, is reported. It allows a fast electronic effect to be separated from a slow thermal effect, which often masks the accurate measurement of electronic χ(3). This is important when the one- or two-photon absorption is large, which often occurs in organic materials. Using the method, the authors have been able to resolve a nonlinear phase shift of approximately π/500, limited only by the saturation of the broadband (40-MHz) detector preamplifier used.
