Résumé

In this paper, Tm3+ doped fluorotellurite glasses are synthesized by melt-quenching technique. The thermal and spectral properties of the glasses are characterized. The effect of the 1.8 mu m emission properties for different Tm3+ concentrations are investigated. Delta T (153 celcius) of the glass indicates it has good thermal stability. Spectroscopic parameters of Tm3+ such as radiative transition probability, branching ratio, spectroscopic quality factor, integrated emission cross section and radiative lifetime are calculated on the basis of Judd-Ofelt analysis. The maximum half-height width corresponding to 1.8 mu m broadens as Tm3+ increases and reaches a maximum of 216 nm, as well as the longer lifetime (5.68 ms). For 1.8 mu m (3F4 -> 3H6) emission band, the calculated Tm3+ doped fluorotellurite glass has a high quantum efficiency of 75.93%. Furthermore, the theoretical analysis of the energy transfer mechanism between Tm3+ ions were represented. Therefore, these results demonstrate that prepared Tm3+ doped fluorotellurite glass is an ideal laser material for 1.8 mu m band solid-state laser applications.
