Third-order optical nonlinear characterizations of glasses in Bi 2 O 3 -B 2 O 3 -TiO 2 ternary system were investigated using femto-second Z-scan method at 800 nm. Results show that third-order optical nonlinearities are influenced by TiO 2 concentration, the largest value of nonlinear refraction g
The results of the femtosecond time-resolved optical Kerr at 820 nm in GeS 2 -In 2 S 3 chalcogenide glasses indicate that the response time in GeS 2 -In 2 S 3 glasses is subpicosecond, which is predominantly due to the distortion of the electron cloud. The value of v (3) in 0.95GeS 2 -0.05In 2 S 3 g
