“…Phosphate glass doped with Re 3+ ions is far from many other materials in terms of realizing photonic materials with enhanced optical gain across a short length while minimizing nonlinear optical consequences, thus leading to highlaser reliability and long-term stability [3,22,23]. Lead phosphate glasses with Re 3+ ions are part of an enormous family of heavy metal glasses explored for potential optoelectronic characteristics as prospective laser glass hosts [24].…”

“…The molten glassy sample was poured into preheated stainless steel frames, followed by transferring the poured sample into another furnace at 300 °C to avoid thermal stress and let to cool gradually till it reached room temperature after 24 h. The obtained sample was divided into rectangle pieces and power for different measurements [42,43]. According to the chemical composition formula, the sample has density of 4.15 g/ cm 3 . The raw materials used for preparation are ammonium dihydrogen phosphate, sodium carbonate, aluminum oxide, lead oxide, erbium oxide, and ytterbium oxide.…”

Herein, this study intends to reveal the impact of gamma irradiation on the structural, linear, and nonlinear optical characteristics of 47P2O5−23Na2O−6Al2O3−22PbO−0.5Er2O3−1.5Yb2O3 glass. The Er/Yb-doped lead phosphate glass samples were produced using the traditional melt quenching procedure and then treated to different doses of gamma irradiation (0, 20, 50, and 100) kGy. The amorphous phase structure of the Er/Yb-doped lead phosphate glass samples was verified through XRD patterns. Also, the shift of the FTIR peaks due to the change in bond angles, and the change in the bond length of the P–O–P bridges means the glass network stability against radiation. With increasing irradiation dosages, the energy gap dropped from 4.11 eV to 3.42 eV and then enhanced to 3.48 at 100 kGy. At the same time, the Urbach energy enhanced from 10.23 eV to 37.03 eV. The oscillator energy Eo was found between 1.55 and 1.62 eV. Also, the dispersion energy Ed varied between 2.11 eV at 100 kGy and 2.71 eV at the dose of 50 kGy. The percentage of free carrier ions to effective mass (N/m*) is in the range (4.82–8.66) × 1047 cm3/g. Besides, the lattice dielectric constant ($${\varepsilon }_{l}$$ ε l ) increased from 5.54 to 6.63 as the gamma dosages increased. Furthermore, increasing gamma doses up to 50 kGy promotes susceptibility, which subsequently declines at 100 kGy, suggesting that increasing gamma doses over 50 kGy weakens polarizability potential. While the increasing gamma doses up to 50 kGy reduces the nonlinear refractive index and then improves at 100 kGy. Overall, the nonlinear and linear research revealed that Er/Yb lead phosphate glass is being used as a promising material for gain media and optical amplifiers.
