We have demonstrated anomalous-dispersion phase-matched second-harmonic generation, using electric-field-induced second-harmonic generation in a liquid solution of Foron Brilliant Blue S-R (FBB). This dye has a sharp absorption maximum near 620 nm and a deep absorption minimum near 450 nm. The microscopic hyperpolarizability ({beta}) of FBB was measured at 1.58 and 0.954 {mu}m and was found to be 163 {times} 10{sup {minus}30} and {minus}118 {times} 10{sup {minus}30} cm{sup 5}/esu, respectively. The change in sign of {beta} and the observation that {beta}{sub 0}, a frequency-independent measure of hyperpolarizability, is the same at both frequencies demonstrate the validity of the two-state model of the second-order hyperpolarizability.
