设计了一种新型的铒、镱共掺高增益光纤材料,分析了各种组分对氟磷酸盐体系发光性能的影响,制备出热稳定性和机械性能较好(ΔT=141℃)、无析晶、透过率较高的光纤材料。光谱测试结果表明:所制备的光纤芯材料具有较高的吸收截面(2.075 pm2)、较高的发射截面(1.11 pm2)、较长的荧光寿命(7.30 ms)和高的增益品质系数(74.099×103pm3),是优良的高增益、宽带宽的光纤放大器增益材料。
A new erbium and ytterbium codoped high gain fiber material was designed. The effects of various components on the luminescent properties of the fluorophosphate system were analyzed. The results showed that the thermal stability and mechanical properties were better (ΔT = 141 ℃) Crystallization, high transmittance of optical fiber materials. The results of spectral test showed that the prepared optical fiber core material has high absorption cross section (2.075 pm2), high emission cross section (1.11 pm2), long fluorescence lifetime (7.30 ms) and high gain quality coefficient (74.099 × 103pm3), is an excellent high-gain, wide-bandwidth fiber amplifier gain material.
