Nd3+-doped oxyfluoro-titania-phosphate glasses with a chemical combination, P2O5–CaF2–BaF2–TiO2–Nd2O3 (PCfBfTiNd), were synthesized by the regular melt-quenching method. These glass samples were investigated through optical absorption, emission, decay curves and spectroscopic ellipsometry analysis. Non-linear refractive index (n2) is evaluated using the Boling method and it was found to be as low as 3.68 × 10−16 cm2/W (1.36 × 10−13 esu). Emission spectra of Nd3+-doped glasses were obtained by laser excitation at a wavelength of 808 nm. Results were endorsed that the 0.5 mol% Nd3+-doped PCfBfTiNd05 glass could be a suitable gain media for the development of high-energy high-peak power lasers.
