    • Abstract
  • The nonlinear optical properties of a novel dmit2- salt:(tetramethylammonium)bis(1,3-dithiole-2-thione-4,5-dithiolato) copper(abbreviated as MeCu) are studied with z-scan technique at 1064nm with 30ps laser duration.The nonlinear refraction coefficient n2 and the second hyperpolarizability γ have been determined to be -2.15×10-11 esu and 1.94×10-30 esu,respectively.No nonlinear absorption is observed under this condition.All the results show that MeCu is a potential material for nonlinear optical devices such as all-optical switches.
