纳米级掺稀土非氧化物团簇复合在氧化硅玻璃中,可以结合非氧化物玻璃和氧化物玻璃在光放大和化学、热力学、力学等方面各自的优点,提供可以应用于实用化1.3μm,宽带1.5μm和新发展的1.4μm光放大的新材料。在一种复合材料中,峰值位于1315nm的荧光峰及线型被证实与用来进行复合的掺稀土氟镓锆玻璃中的峰完全一致,而在复合材料中其荧光寿命较长。以Pr3+和Nd3+作为活性离子的复合材料的吸收谱线宽比Pr3+和Nd3+掺杂的ZBLAN的相应吸收谱线宽展宽最多达到10nm。复合材料的光谱性质有利于器件增益并放宽对泵浦光源的要求。
Nanometer rare earth doped non-oxide clusters in the silica glass, the combination of non-oxide glass and oxide glass in the optical amplification and chemical, thermodynamic, mechanical and other aspects of their respective advantages, to provide can be applied to practical 1.3μm, Broadband 1.5μm and newly developed 1.4μm optical amplification of new materials. In a composite, the fluorescence peak at 1315 nm and its linear peak were confirmed to be in good agreement with the peaks in the rare earth doped gallium arsenide zirconium used for the composite, while their fluorescence lifetime was longer in the composite. The absorption spectrum of ZBLAN doped with Pr3 + and Nd3 + doped with Pr3 + and Nd3 + as active ions is widened by up to 10 nm. The spectral properties of the composite material contribute to the gain of the device and relax the requirements of the pump light source.
