Abstract
Large nonresonant third-order hyperpolarizabilities, γ1111, for solutions of three organic charge-transfer complexes in tetrahydrofuran have been measured. The values obtained for nonresonant γ1111 are 5.8×10−32 esu for Perylene/tetracyanoethylene, 1.2×10−32 esu for Pyrene/tetracyanoethylene, and 7.2×10−33 esu for Naphthanthracene/tetracyanoethylene. The corresponding values of the third-order susceptibility χ(3)1111 for the solid state are estimated to be 1.0×10−9 esu, 2.3×10−10 esu, and 1.3×10−10 esu, respectively.Keywords
