Spectral Properties of ～2 μm Emission of Tm3+ Doped Bi2O3-SiO2-PbO Glass
摘要
Abstract
Silicate glasses 33Bi2O3-50SiO2-17PbO doped with 0.1%,0.25%, 0.5%, 0.75% and 1% Tm2O3 were prepared by the conventional melting method. Thermal property was studied by the DSC (Differential Scanning Calorimeter) method. Its Tx-Tg value is 138℃. According to the absorption spectra and Judd-Ofelt theory, J-0 strength parameters, radiative transition properties, the radiative lifetimes and the branching ratio of some excited state energy levels were calculated. Analysis on the relationship between 3F4 lifetime and Tm3+ doped concentration showed that the critical concentration for self-quenching is 3.54×1020 ions/cm3. The absorption and emission cross-sections of Tm3+: F4→3H6 transition were obtained using McCumber theory. The maximum absorption cross-section is 3.7×10-21 cm2 at 1658 nm and the maximum emission cross-section is 7.2×l0-21 cm2 at 1842 nm. The results show that Tm3+ doped 33Bi2O3-50SiO2-17PbO material is an ideal candidate to realize ~2 μm laser.关键词
