2014
Optical Materials Express
Chalcogenide glasses from (GeSe 2 ) 100-x (Sb 2 Se 3 ) x system were synthesized, with x varying from 5 to 70, in order to evaluate the influence of antimony selenide addition on nonlinear optical properties and photosensitivity. Nonlinear refractive index and two photon absorption coefficients were measured both at 1064 nm in picosecond regime using the Z-scan technique and at 1.55 µm in femtosecond regime using an original method based on direct analysis of beam profile change while
