The investigation on the spectroscopic properties of Er^(3+)/Yb^(3+) co-doped fluorophosphate glass

氟磷酸盐玻璃由于其特殊的光学性能与优良的机械性能一直是特种玻璃材料领域内一个研究热点,本文研究了Er3+/Yb3+共掺氟磷酸盐玻璃的吸收光谱,荧光光谱,测得了Er3+离子4I13/2能级荧光寿命,并计算了其吸收与发射截面,实验结果显示Er3+/Yb3+共掺氟磷酸盐玻璃具有带宽宽,增益平坦的特点,是一种能作为实现超短脉冲输出的激光器和光纤放大器的基质玻璃材料.

Fluorophosphate glass is an important subjet in the field of special optical glasses materials,due to its excellent optical properties and good mechnical peoperties.In this paper,the absorption spectra,emission spectra,and the lifetime of 4I13/2 energy level of Er3＋,is investigated.we calculated the absorption cross-section and emission cross-section.these resultes indicate the fuorophosphate glass is candidate as the media for the broad-band,flat gain and the generation of ultrashort pulses and fiber amplifer.
