摘要：

The third-order optical nonlinearity chi((3)) of two novel guest-host polymers has been measured. The polymers consisted of nickel dithiolene guest molecules in a polymethylmethacrylate host and were prepared as cast or spun films. The optical nonlinearity was measured by degenerate four-wave-mixing experiments at a wavelength of 1.06-mu-m using 100-ps laser pulses. chi((3)) coefficients of up to 10(-17) m2/V2 were observed, corresponding to nonlinear refractive index n2 of up to 10(-8) cm2/kW with a damage threshold > 1 GW/cm2.
