对于吸收带在0.77和1.06μm之间的镍二硫纶配合物，在1.06μm处测量了三阶光学非线性系数χ（3）、线性吸收系数α和χ（3）的真实的实部与虚部之比。根据这些数据，计算非线性回缩指数n2和基于器械的品质因数W（=Δnsat/αλ）。对于最大吸收低于0.8-0.85µm的材料，发现W超过2。在聚甲基丙烯酸甲酯基质中掺入8 × 10 ~（-19）分子cm ~（-3）的二硫纶镍，其非线性折射率接近2 × 10 ~（-9）cm ~ 2·kW ~（-1）。
The third-order optical non-linearity, χ(3), linear absorption coefficient, α, and the ratio of the real to imaginary parts of χ(3)have been measured at 1.06µm for a range of nickel dithiolene complexes with absorption bands between 0.77 and 1.06µm. From these data the non-linear retractive index, n2, and the device-based figure of merit, W(=Δnsat/αλ), were calculated. W was found to exceed 2 for materials with absorption maxima below 0.8–0.85µm. The non-linear refractive index of a poly(methyl methacrylate) host doped with 8 × 1019 molecules cm–3 of a nickel dithiolene was also measured and found to be nearly 2 × 10–9cm2 kW–1.
