摘要

采用熔融淬冷法制备了两种浓度的Pr,3+,掺杂GeSe,2,-Ga,2,Se,3,-CsI(GGC)硫卤玻璃。在2.0 μm激光激励下，比较了玻璃片(2 mm)和玻璃柱(6 mm)的荧光发射光谱。用Judd-Ofelt理论计算分析了Pr,3+,掺杂Ge-Ga-Se-CsI硫卤玻璃的强度参数,Ω,i,(,i,=2，4，6)和辐射寿命,τ,rad,等光谱参数。通过拟合衰变曲线，测得了玻璃的荧光寿命值(0.5% Pr,3+,:3.08 ms)。所制备的光纤具备双包层结构，通过截断法得到光纤在7.6 μm处的最低损耗为2.27 dB/cm。

Abstract

Different series of Pr,3+, doped GeSe,2,-Ga,2,Se,3,-CsI(GGC)chalcogenide glass were prepared by a melt-quenching method. Under the excitation of 2.0 μm wavelength, the emission spectra of bulk glass (2 mm) and glass column(6 mm) were compared. The intensity parameter ,Ω,i,(,i,=2, 4, 6) and radiative lifetime ,τ,rad, of Pr,3+, doped Ge-Ga-Se-CsI chalcogenide glass are calculated and analyzed by Judd-Ofelt theory. The fluorescence lifetime of the glass(0.5% Pr ,3+,:3.08 ms) was measured by fitting the decay curve. The fabricated fiber has a double cladding structure, the fiber loss is measured by cut-back method and the minimum loss at 7.6 μm is 2.27 dB/cm.
