Paper Abstract

In this work, we present a study of the third-order non linearities of two derivatives of the organic molecule 2- amino-1,2,3 triazole-quinone. The absorptive and refractive contributions to the nonlinearity were resolved using the z- scan technique with a 88ps pulse source at 532nm. For one of the materials, the open aperture z-scan result show a nonlinearity arising from a combination of two-photon and saturable absorption, and the closed aperture the signature of a negative n2.
