Abstract
The frequency dependence of the first molecular hyperpolarizability β of a thiophene based charge-transfer chromophore was measured. A number of excitation wavelengths emitted from an optical parametric amplifier pumped by a 1 KHz 130 fs Ti/sapphire laser were used. It was observed that the excitation wavelength covers the resonance and nonresonance region of the charge transfer chromophore.
