Nonlinear optical properties of new molecular crystals

Abstract

P-p'-dioxydiphenylsulpfone, p-nitro--p'-methylbenzylidenaniline, 3-metoxy-4--oxybenzaldehyde crystals are obtained of high optical quality. Refraction index dispersion, nonlinear susceptibility tensor components values, symmetry classes are determined. It is shown that the crystals posses high nonlinear susceptibility along with wide range of transparency and high laser damage threshold. A new method is considered of nonlinear susceptibility measurements.
