摘要
本文从理论上通过对钕玻璃中Nd~(3+)离子光吸收特性的分析,阐明了其光吸收对温度依从性的原因.在实验中,试制了几种不同类型的钕玻璃光纤温度传感探头.对Nd~(3+)离子光吸收的温度特性进行了验证,其结果和理论分析相一致,实验表明钕玻璃是一种性能良好的光纤温敏传感材料.
The absorption of Nd3+ doped glass is analysed on theory and indicates the reason
of temperature dependent absorption of Nd3+. In experiment, the severeal kinds of probe with Nd3+ doped glass core are made. The experimental results agree with theory analysis. The results demonstrate that Nd3+ doped glass is one of superior temperature sensing material.
