Here we disclosed the substantial effect of the local medium in the vicinity of the excited Nd(3+)ions on the optical properties and the laser characteristics of glasses. The UV-Vis absorption of the laser BaO/SrO-P2O5-Al2O3-K2O-B2O3-La2O3 glasses doped with Nd3+ ions is measured at 25 degrees C. Judd-Ofelt (JO) theoretical analysis of 4f electron transitions in the Nd3+ absorption spectra was performed. From the JO intensity parameters, a set of the laser (F3/2I11/2)-F-4-I-4 transitions characteristics are found and stimulated emission cross-sections are characterized. The effect of different Ba/Sr ratio on the structure-properties relationships in the glasses is shown.
