Nonlinear refractive analisys of Dy3+ doped TeO2ZnO glasses

Abstract

Here, we report CA Z-Scan results for 80TeO2.20ZnO:xDy3+ glasses (x =1.0,2.0mol%). Both samples presented a self-focusing lens like behavior, with a nonlinear refractive index varying from (5.87 ± 0.04)10 − 15 cm2/W to (20.37 ± 0.09)10 − 15 cm2/W.
