中文摘要: 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1000~1700 nm,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。
Abstract: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.
