有机金属α-[bis（ethylenedithio）tetrathiofulvalene] 2 I3在650 nm附近表现出很大的三阶光学非线性，这是通过前向简并四波混频观察到的。沿最大电导率方向观察到了沿着方向的非线性极化率，极化率为5×10−8 esu。非线性的频率色散指向由于传导电子引起的等离子体效应。
The organic metal α‐[bis(ethylenedithio) tetrathiofulvalene]2I3 shows a large third‐order optical nonlinearity around 650 nm, as observed by forward degenerate four‐wave mixing. Nonlinear susceptibilities of ‖χ(3)‖ ∼5×10−8 esu are observed along the direction of maximum conductivity. The frequency dispersion of the nonlinearity points to a plasma effect due to the conduction electrons.
