Abstract

The two-photon absorption spectrum of a nickel bis(dithiolene) complex with extended conjugation and pi-donor substitution is measured by using Z-scan and pump-probe techniques with femtosecond pulses over the spectral range from 1.20 to 1.58 mu m, which includes much of the telecommunications range. The peak two-photon cross section of over 5000 GM (1 GM = 10(-50) cm(4)s photon(-1) molecule(-1)) occurs at similar to 1.24 mu m, with significant two-photon absorption (> 440 GM) throughout the spectral range examined.
