Abstract
ABSTRACTHere we disclosed the substantial effect of the local medium in the vicinity of the excited Nd3+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 °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 4F3/2→4I11/2 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.
