摘　　要：用三维简并四波混频实验研究了所合成的４种萘醌并噻唑，四氧二苯并噻蒽化合物的三阶非线性光学性质。采用相对测量法测得样品溶液的χ（３）≌４×１０－３ｅｓｕ，分子的三阶超极化率γ≌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 four dioxonaphthothiazole and tetraoxodibenzothianthrene compounds were studied with 3D DFWM. By using the relative measurement technique, the thirdorder nonlinear optical susceptibilities |χ(3)| and the hyperpolarizabilities γ of the compounds were as large as 4×10-13 esu and 4×10-31esu respectively. The influence of the molecular structure on the thirdorder nonlinear properties of the materials was analyzed.
