ABSTRACT
In this chapter, the authors add nonlinear refractive index measurements for organic binary liquids, crystals, guest-host polymers, amorphous polymers, polymeric crystals, dye-doped glasses, organic metals, and dye solutions. There has been extensive work in time-domain studies. When the dispersion of the nonlinear refractive index is reported, the authors list only those discrete wavelengths over which the nonlinear refractive index changes appreciably. The accuracy of such transcription usually greatly exceeds the quoted experimental uncertainties. The notation for describing the composition of these systems is left as reported in the original work. Solute concentrations are therefore given in terms of the optical density of the material, absorbance in a standard cell, weight concentration, or molar concentration. Both the solid and liquid solution materials are interesting because they have a third-order susceptibility that is generally linear in dye density for low concentrations.
