讨论了有机生色团和极化聚合物膜的二阶非线性光学特性的非激光测试和评估方法，它包括测定生色团分子一阶超极化率（β）的溶剂化变色法、测定极化膜的ｄ值的电子吸收光谱法和偏振红外光谱法以及相应的简化估算公式，在此基础上还提出了极化膜进行应用试探的筛选标准。方法简便易行，无需复杂昂贵的激光测试系统，而且结果有较高的精度，适用于普通化学实验室进行样品的评估和筛选。
Non-laser testing and evaluation methods for second-order nonlinear optical properties of organic chromophores and polarized polymer films are discussed, which include a solvatochromic method for the determination of the first-order hyperpolarizability (β) of a chromophore molecule, Polarization film d value of electron absorption spectroscopy and polarization infrared spectroscopy and the corresponding simplified estimation formula, on this basis also put forward the application of polarized membrane screening test criteria. The method is simple and convenient, does not require complicated and expensive laser testing system, and has high precision and is suitable for evaluating and screening samples in common chemical laboratories.
