摘　　要：ASE光源是卫星用高精度光纤陀螺光路的核心部件,光源性能会影响陀螺的噪声、零偏和标度因数稳定性等性能指标。具有高功率、宽光谱的ASE光源能够提升陀螺产品的精度和稳定性。采用双程前向结构完成了宽谱ASE光源的工程化应用设计,最终实现了输出功率≥5 mW、谱宽≥10 nm的典型高斯型宽谱ASE光源在高精度光纤陀螺宇航产品中的批量应用。此外,针对未来高精度光纤陀螺性能进一步提升的需求,采用平坦滤波和高斯滤波相结合的技术完成了谱宽≥20 nm ASE光源的设计及研制。ASE light source is the core component of the optical path of high precision fiber optic gyro for satellite.The performance of the light source will affect the properties of the gyro,such as noise,bias and scale factor stability.High power and wide spectrum ASE light source can improve the accuracy and stability of the gyro product.A double-pass forward optical path structure is designed for the engineering application of a wide spectrum ASE light source.The typical gaussian-shaped wide-spectrum ASE light source with output power higher than 5 mW and spectrum width greater than 10 nm is batch applied in high-precision fiber optic gyro products for aerospace.Furthermore,to further improve the performance of high-precision fiber optic gyro in the future,the design of ASE light source with spectrum width greater than 20 nm is completed by combining flat filter and Gaussian filter.
