Study On Third-order Nonlinear Optical Properties Of [(C4H9)4N]Au(dmit)2 Using Z-scan Technique

A dmit2− salt ([(C4H9)4N]Au(dmit)2) was synthesized and its acetone solution’s third-order nonlinear optical properties were investigated by Z-scan technique using a pulsed laser with 28 ps duration and 10 Hz repetition at 532 nm. The second-order hyperpolarizability for its molecular was estimated to be as large as 2.74×10−31 esu.
