| 摘 要： | 在ZINDO方法的基础上, 按完全态求和公式编制了计算分子的二阶非线性光学系数张量元βijk的程序, 并以此为基础计算了BNPT-DTO, BNPT-DTT分子二次谐波条件下的二阶非线性光学系数, 从分子水平研究了其分子的光学倍频性质及分子倍频与晶体宏观倍频的关系, 计算结果较好地说明了实验现象。

| Abstract: | On the basis of ZINDO method, the program for the calculation of nonlinear second-order optical susceptibilities βijk has been devised according to the formula of sum-over-states and the values of molecules of BNPT-DTO and BNPT-DTT have been calculated under condition of second harmonic generation. The relation of nonlinear second-order optical suseptibilities between molecules and crystals of BNPT-DTO, BNPT-DTT is analyzed at the molecular level, the computation results are in better agreement with the experimental results. |
