Abstract

In this work, we have used a Ti³⁺:Safira laser tuned at 803nm to performed time-resolved measurements using the Z-scan technique to characterize the nonlinear optical properties of phosphate glasses. The glass matrices, labeled PAN (P₂O₅-Al₂O₃-Na₂CO₃) and PANK (P₂O₅-Al₂O₃- Na₂O-K₂O), were doped with increasing Nd³⁺ concentration, ranging from 0.5 to 5 wt%. For both systems, we have seen that the optical nonlinearity has a linear dependence with the doping ion concentration. Therefore, we propose a new approach to obtain the parameters Δα and Δσ. All results obtained are in good agreement with others found in the literature.
