Paper Abstract

The ultrafast third-order nonlinear optical properties of C60+ vinyltriethoxysilane H2C=CHSi(OC2H5)3 (C60+VTES) sol-gel were investigated by the femtosecond optical Kerr gate (OKG) technique at 800 nm. The third-order optical susceptibility was measured to be 5.42 × 10−14 esu for C60+VTES at a weight concentration of 0.06 wt.%. Using C60+VTES as the OKG material, we acquired a series of narrow bandwidth and symmetric gated spectra continuously from the chirped white light continuum generated in water with femtosecond laser pulses. The gated spectra obtained using the C60+VTES OKG have distinct superiorities compared with CS2.
