The Characteristic Spectrum of 1.3 μm Light Amplifying Nanoscale Composite Materials

报告了掺稀土镓锆氟化物玻璃团簇与氧化硅的复合材料的中心在 13 5nm的荧光谱与掺稀土镓锆氟化物玻璃的一致性以及较长的荧光寿命。与标准的掺Pr3 + 和Nd3 + ZBLAN的吸收谱相比较 ,以Pr3 + 和Nd3 + 为活性离子的复合材料的吸收谱线展宽达到 10nm。复合材料的光谱性质可能有利于提高器件的增益并放宽对泵浦光源的要求 .

The composite materials with nanoscale rare earths doped non oxides glass clusters embedded in silica glass may combine the advantages of non oxides glasses and silica glass in light amplifying and in chemical, thermo dynamical, and mechanical properties.These new materials would be suitable for practical 1 3 μm,wide band 1 5 μm, and newly developed 1 4 μm applications.The fluorescence spectrum centered at 1 315 nm of one of the materials was measured identical with that of the rare earth doped gallium zirconium fluoride glass, while the lifetime was marginally longer. The absorption spectral line widths of the composite materials with Pr 3+ and Nd 3+ as active ions were broadened up to 10 nm comparing with the reference line widths of Pr 3+ and Nd 3+ doped ZBLAN. The optical spectroscopy properties of the composite materials may benefit may benefit gain of device and relax the requirement on pumping sources.
