摘　　要：根据三维简并四波混频耦合理论，推导了前向位相共轭光的场强方程．用三维简并四波混频实验测定了１４种吡啶酮偶氮化合物溶液的三阶非线性极化率χ（３），并计算了分子的三阶非线性超极化率γ．结果表明，推拉型吡啶酮偶氮化合物具有较强的三阶非线性光学性能．Based on the theory of 3D DFWM, the equation of the intensity of the forward phase conjugate waves was deduced theoretically. The third order nonlinear optical properties of a series of 14 pyridone monoazo compounds were studied with 3D DFWM geometry. The χ (3) value and the γ value are as large as 4.3×10 -13 esu and 4.5×10 -31 esu respectively. The influence of the molecular structure on the third order nonlinear optical properties of the materials was analyzed.
