- Abstract
We report on the nonlinear (NL) optical properties of glassy TeO-GeO-KO-BiO at λ = 800 nm and λ = 1,064 nm. Using the Kerr gate technique with a laser delivering 150 fs pulses at 800 nm, we demonstrated the fast NL response of the samples. The modulus of the NL refractive index, n, at 800 nm was ~10 cm/W. The Z-scan technique was used to determine n ≈ +10 cm/W, at 1,064 nm with pulses of 17 ps. The two-photon absorption coefficient, α, was smaller than the minimum that we can measure (<0.003 cm/GW). The figure of merit n/ α λ was calculated and indicates that this glass composition has large potential to be used for all-optical switching.
