Er3+/Yb3+/P5+共掺杂石英纤芯玻璃吸收和能量转移效率的温度依赖性
Listed in ScienceDB
Description
采用溶胶-凝胶法结合高温烧结法制备了高磷Er3+/Yb3+共掺杂二氧化硅（EYPS）纤维芯玻璃。在300至480K的温度范围内，测量并比较了吸收光谱、发射光谱和荧光衰减曲线。与915和97x纳米相比，~940纳米的吸收截面（~0.173pm2）显示出较弱的温度依赖性。因此，940纳米的泵浦机制对于实现1.5微米的高功率激光输出是有利的。此外，Yb3+离子的双指数荧光衰减和I1018nm/I1534nm的发射强度比被测量，以评估从Yb3+离子到Er3+的能量转移效率。通过外部加热和主动量子缺陷加热方法，I1018nm/I1534nm的发射强度比从~300到~480K分别增加了30.6%和709.1%。结果表明，温度的上升大大降低了从Yb3+到Er3+离子的能量转移效率。
