Abstract
We present the measurement of the third-order nonlinearity of Bi2O3-B2O3-BaO glasses using the single Z-scan method with femtosecond laser pulses at 750-850 nm. Both third-order nonlinear refraction γ and two photon absorption coefficient β are investigated. The γ shows an increasing tendency with increasing BaO content, and the largest value is estimated to be 7.2×10-14 cm2/W, which is as large as those of chalcogenide glasses. The dependence of β on the normalized photon energy is studied.
