This work investigates the effect of sodium incorporation on the laser spectroscopic properties and C-band optical gain of Er3+-doped zinc phosphate glasses. Two glass compositions-zinc phosphate (ZPO) and sodium-zinc phosphate (NZPO)-were synthesized and characterized through absorption and emission spectroscopy. The Judd-Ofelt theory was applied to determine the intensity parameters (522, 524, 526), from which radiative properties such as spontaneous emission probabilities, branching ratios, and lifetimes were derived. Emission and absorption cross-sections were calculated, and the theoretical on-off gain was estimated and compared to experimental measurements. The results reveal that NZPO exhibits enhanced optical performance, including higher ae, broader effective bandwidth, and greater theoretical and experimental gain values. The increase in 522 and 526 in NZPO indicates stronger ion-ligand interaction and improved radiative efficiency, making sodium-zinc phosphate glasses promising candidates for C-band optical amplifiers and laser applications.
