Abstract :
We report on the systematic, broadband characterization of the third-order nonlinearities of the commonly used reference materials: sapphire, the lead-silica glass SF-59 and pure carbon disulfide CS/sub 2/. Using the z-scan technique with /spl sim/1-ps pulses experimental data on the nonlinear refraction and two-photon absorption were obtained in the 550-1600 nm wavelength range. Theoretical treatment of spectra and scaling of the measured nonlinearities in sapphire and SF-59 glass is given using a simple Kramers-Kro/spl uml/nig transformation-based model. Compact empirical relations are suggested.
