ABSTRACT
The nonlinear refraction coefficient of silica aerogel was estimated to be ∼-1.5 × 10[SUP-15]m[SUP2]/W (∼-3.67 × 10[SUP-9] esu) with a signal-beam z-scan spectroscopy. The third-order nonlinear refraction coefficient of nanostructure silica aerogel was almost five orders larger than the nonlinear refraction (χ[SUP3]) of bulk material. The large nonlinear refraction with high nonlinear figure of merit is an ideal optical property for nonlinear optical applications.
