摘要
研究了输出谱型为近高斯型的掺铒超荧光光纤光源,分析了高斯型光谱的自相干函数和影响平均波长稳定性的因素.采用双程前向光源结构,通过选择铒纤长度获得高斯型光谱输出,同时调节泵浦功率来优化铒纤的本征温度系数对光源的影响,得到铒纤长度10.05 m,泵浦功率为172 mW时,整体光路(除半导体泵浦激光器及其驱动电源)在全温-40℃~60℃测试条件下平均波长稳定性为66.651 ppm的近高斯型掺铒光纤光源.
The on near Gaussian-shaped spectrum Erbium-doped fiber super-flourescent source was studied.The self-coherence function of Gaussian-shaped spectrum and the change of mean wavelength under different temperatures were theoretically analyzed.Using the double-pass forward configuration,the Gaussian-shaped spectrum was obtained with certain Erbium-doped fiber length.Meanwhile,pump powers could be adjusted to optimize the intrinsic thermal coefficient of Erbium-doped fiber.Finally,under the condition with erbium-doped fiber length of 10.05 m,LD power of 172 mW,the whole optical path(except pumping LD and the driving) in the environmental temperature from-40 ℃ to 60 ℃,the near Gaussian-shaped spectrum Erbium-doped fiber source with 66.651 ppm mean wavelength stability was obtained.
