Abstract

Based on the anionic group theory, a computer-assisted material design system (CAMDS) has been developed and shown to be a highly efficient means for discovering nonlinear optical crystals. In this method, important optical properties of the target compounds (borates, for example), such as the d_ij coefficients, refractive indices and energy bandgap, are calculated so that a prior evaluation can be made before experiments. The results have given a meaningful guide to ensuring experiments, which have led to our discoveries of KBBF (KBe₂BO₃F₂) and SBBO (Sr₂Be₂B₂O₇) in previous years followed by other members of the SBBO family in recent years. On the other hand, the system can also be used to evaluate the d_ij coefficients of the borate NLO crystals discovered recently whose d_ij coefficients have not been determined from experiment.
