The third-order optical nonlinearity was measured in bismuth-based glasses by Z-scan technique using femto-second laser pulses. Re(v (3) ) = 4.9 β€’ 10 Γ€11 esu at 748 nm was obtained in the glass containing 65.5 mol% of Bi 2 O 3 . Although, the wavelength dependence of Re(v ( 3) ) shows resonant effec
