In the present study new results are reported concerning the nonlinear optical response of a gold dithiolene complex, namely the [Au(dpedt)2]. The nonlinear optical properties of the dithiolene are investigated using 35ps and 4ns laser excitation, both in the infrared (1064nm) and in the visible (532nm), by means of the Z-scan technique. In all cases, the nonlinear optical absorption coefficient β, the nonlinear refraction parameter γ′ and the third-order susceptibility χ(3) have been determined and the second hyperpolarizability γ was obtained. The present results are discussed and compared with previously reported data of similar dithiolene complexes.
