摘要
为了获得高稳定的光纤陀螺掺铒光纤光源,理论分析了平均波长受温度变化的影响因素,实验研究了双程前向(DPF)结构掺铒光纤光源平均波长温度稳定性。主要通过优化铒纤长度来减小铒纤的本征温度系数对光源稳定性的影响,优化泵浦功率使其引起平均波长的变化达到最小。最终获得了掺铒光纤光源在双程前向结构下的优化铒纤长度12.2m和优化泵浦功率150mW,对比分析了包括优化铒纤长度在内的三个长度下,不同泵浦功率对光源的平均波长、输出功率和谱宽的影响;测量了不同长度铒纤的本征温度系数,获得了平均波长稳定性为-0.452ppm/°C的双程前向光纤光源。
In order to obtain high stability fiber optic gyroscope erbium-doped fiber source, the influence factors of temperature changes on the mean wavelength are theoretically analyzed. The mean wavelength temperature stability of double-pass forward （DPF） erbium-doped fiber source is studied experimentally. Optimized erbium-doped fiber length 12.2 m and pump power 150 mW in DPF fiber source are obtained. Using three fiber lengths including optimized fiber length, the influences of different pump power on mean wavelength, output power and spectral width of fiber source are analyzed. The intrinsic thermal coefficients of different length fiber are measured. The DPF fiber source with -0.452 × 10^-6/℃ mean-wavelength stability is obtained. K
