The third-order optical nonlinearity χ[SUP(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 μm using 100-ps laser pulses. χ[SUP(3)] coefficients of up to 10[SUP-l7] m[SUP2]/V[SUP2] were observed, corresponding to nonlinear refractive index n[SUB2] of up to 10[SUB-8] cm[SUP2]/kW with a damage threshold > 1 GW/cm[SUB2].
