Nonlinear refractive-index measurements of glasses using three-wave frequency mixing
TLDR
In this article, the nonlinear refractive index of transparent materials is measured relative to that of a standard with a known index, and the relationship between the observed nonlinear index and the structure and composition of the glasses is discussed.Abstract:
We have developed a rapid and accurate method for measuring the nonlinear refractive index of transparent materials. It is based on a version of three-wave mixing in which the frequencies of the two input beams are adjusted to differ by about 60 cm−1. The nonlinear index of a material is measured relative to that of a standard with a known index. Our measurements of 27 glasses are in good agreement with previous results, where available, and with the n2 values calculated empirically from linear index parameters. We also discuss the relationship between the observed nonlinear index and the structure and composition of the glasses.read more

Empirical Relation between the Linear and the Third-Order Nonlinear Optical Susceptibilities
TL;DR: In this article, a simple empirical relation is found between the linear and the third-order nonlinear optical susceptibilities for gases at low pressures, and its applicability to crystalline solids and its bearing on the generalized Miller's rule for these solids is discussed.

Empirical relationships for predicting nonlinear refractive index changes in optical solids
TL;DR: In this article, a number of authors have proposed empirical relations between the nonlinear index and linear dispersion parameters, and they have shown that the major differences arise in the treatment of local field corrections, due to the fairly large experimental uncertainty and the fact that all the materials investigated to date are really quite similar, being essentially oxide or fluoride materials.
