摘　　要：由于具有质量轻与成本低等优点,光纤陀螺正在被广泛应用,而光源光谱的特性在很多方面又影响着光纤陀螺的性能。利用新型光纤制备技术,制备铋/铅共掺石英光纤,测试分析其吸收光谱与发光特性。用980nm与830nm双泵浦光激发,超宽带荧光光谱范围可覆盖1000～1700nm,相比单泵情况,光谱大大拓宽。10dB带宽的光谱达到了650nm,光谱比较平坦,可以满足超宽带平坦光源的需要,并可作为超宽谱光源的理想增益介质。对应用于惯性导航系统、光纤陀螺传感器(Fiber Optic Gyroscopic Sensor,FOG)、光学相干断层扫描系统(Optical Coherence Tomography,OCT)与医学成像的超宽谱光源进行研究,具有非常重要的实际应用与战略意义。Fiber optic gyroscope,with the advantages of light quality and low cost,is widely used,and the performance of gyroscope is affected by the spectral characteristics of light source in many aspects.Bi/Pb co-doped silica fiber is fabricated using a novel optical fiber fabrication technology.Then,the absorption and fluorescence spectra have also been analyzed.The ultra-broadband fluorescence spectrum ranges from 1000~1700nm,using double pumping power of 980nm and 830nm.The bandwidth at 10dB is 650nm.In addition,the fluorescence spectrum is relatively flat,and conforms the need of ultra-broadband flat light source,which can be used as the desired gain medium of ultra-broadband light source.Therefore,the research of Bi/Pb co-doped silica fiber can be applied in inertial navigation system,fiber optic gyroscopic sensor,optical coherence tomography and medical imaging system,and so on.It has a very important significance of practical and strategic.
