Abstract
The two-photon absorption spectrum of a nickel bis(dithiolene) complex with extended conjugation and π-donor substitution is measured by using Z-scan and pump–probe techniques with femtosecond pulses over the spectral range from , which includes much of the telecommunications range. The peak two-photon cross section of over occurs at , with significant two-photon absorption throughout the spectral range examined.
