摘　　要：用三维简并四波混频（ＤＦＷＭ）研究了五种萘醌并噻唑化合物的三阶非线性光学性质。实验测得样品溶液的三阶非线性极化率｜χ（３）Ｓ｜４．３×１０－１３ｅｓｕ，分子的三阶非线性超极化率γＳ４．４×１０－３１ｅｓｕ。分析了分子结构对三阶非线性光学性质的影响。Third order nonlinear optical properties of a series of 5 dioxonaphthothiazole compounds were studied with three dimensional degenerate four wave mixing. The third order nonlinear optical susceptibilities |χ (3) | and the third order hyperpolarizabilities γ of dioxonaphthothiazole compounds were measured to be 4.3×10 -13 esu and 4.4×10 -31 esu respectively. The influence of the molecular structure upon the third order nonlinear properties of the materials was analyzed.
