对非线性光学有机材料（-）2-（α-甲基苄胺）-5-硝基吡啶（MBANP）进行了全面研究，目的是将其应用于激光二极管的倍频器件中。其分子超极化率与对硝基苯胺相当。MBANP以高度不对称的分子排列结晶。最大非线性光学系数d22测得为60 pm/V。在1.064µm处倍频的相应优点值是LiNbO3的d33的3.5倍。Čerenkov-radiation-type，通过使用适当的波导结构，利用d22系数证明了相位匹配的二次谐波产生。
A nonlinear optical organic material, (-)2-(α-methylbenzylamino)-5-nitropyridine (MBANP), has been comprehensively investigated with the objective of application to frequency doubling of laser diodes. Its molecular hyperpolarizability is as large as that of p-nitroaniline. MBANP crystallizes with a highly asymmetric molecular arrangement. The largest nonlinear optical coefficient, d22, is measured to be 60 pm/V. The corresponding figure of merit for frequency doubling at 1.064 µm is 3.5 times larger than that for d33 of LiNbO3. Čerenkov-radiation-type, phase-matched second-harmonic generation has been demonstrated utilizing the d22 coefficient by making use of an appropriate waveguiding structure.
