摘要: A dmit2- salt: [(C 4 H 9 ) N]Au(dmit) 2 was synthesized. Its third-order nonlinear optical properties of its acetone solution were investigated by Z-scan technique using a pulsed laser with 28 ps duration and 10 Hz repetition at 532 nm. The refractive index n absorption coefficient β the sample obtained to be about 4.997×10−12 esu 1.818 cm/GW concentration 2×10−3 M. second-order hyperpolarizability for molecular estimated as large 2.74×10−31 esu, suggesting is promising material all-optical switching.
