Abstract
The thirdorder nonlinear optical properties of two Audmit2/PMMA compound thin films hexadecyltrimethylammonium bis13dithiole2thione45dithiolatoaurate and tetramethylammonium bis13dithiole2thione45dithiolatoaurate abbreviated as MeAu and CtAu respectively with a doping concentration of 1 wt deposited on quartzglass substrate were characterized by a single beam Zscan technique at 1064 nm with 20 ps laser pulse width and 10 Hz repetition rate The dominant nonlinear refraction and tiny nonlinear absorption of both materials lead to a larger possibility for them to be applied as promising candidates of alloptical switching The results of two figures of merit W≫1 and T≪1 were also calculated this further validated the excellent properties of the materials for applications of the nonlinear opticsThe authors acknowledge the financial support of the Fundamental Research Funds for the Central Universities and the Youth Scientist Fund of Shandong Province BS2011CL025 and the Funds for Foster the Improvement of Subject Innovation Ability of China University of Mining and Technology 2011XK07
