Abstract
The influence of phosphate content on the formation and luminescent properties of Nd3+-doped fluorophosphate glass has been studied. Using the Judd-Ofelt theory the phenomenological intensity parameters Ωt (t= 2; 4; 6) were obtained. Absorption and emission measurements are performed in order to evaluate the spontaneous emission probability, absorption cross-section, emission cross-section, fluorescence lifetime and quantum efficiency. The stimulated emission cross-sections 4F3/2→4I11/2 and transitions were determined according to J-O theory by the modified reciprocity method (MR) for all phosphate concentrations and theoretical gain cross sections have been calculated. The effects of the glass rigidity and phosphate presence in glass composition on radiative properties have been estimated. In order to evaluate the amplification properties of studied samples at 1.06 μm, gain/loss spectra for glass with 5 mol.% of Ba(PO3)2 and commercial Nd3+-doped glass were experimentally obtained. Comparison with commercial Nd3+ doped glass showed that fluorophosphate glass has a higher gain of 1.8 dB/cm.
