New chromophores for second-order nonlinear optical materials, N-cyano-N′-diethylaminophenyl-1,4-naphthoquinonediimines, were proposed. The electro-optic poled polymers showed large second-order nonlinear hyperpolarizability (μβ) in a constant electric field at incident irradiation wavelength of 1.3 μm, being 4 - 6 times than that of commonly used Disperse Red 1.
提出了新的用于二次非线性光学材料的色团,即N-氰基-N′-二乙氨基苯肼-1,4-萘醌二亚胺。电光极化聚合物在1.3微米的入射辐射波长下,在恒定电场中显示出较大的二次非线性超极化率(μβ),是常用的分散红1的4到6倍。
