研究了双程后向结构掺铒光纤光源的平均波长对泵浦功率的依赖性。实验结果表明，通过采用掺铒光纤滤波器以及选择合适的泵浦功率，平均波长随泵浦功率的变化能够降低到-9 ppm/mW。在-40~+60℃温度范围内，光纤光源的平均波长不稳定性小于33 ppm (峰峰值)。采用5 m长的掺铒光纤、泵浦功率55 mW与泵浦波长974.2 nm时，光纤光源输出光波的谱宽达到17 nm，功率达5.83 mW。

The mean wavelength dependence on pump power in an Er- doped superfluorescent fiber source of double-pass backward configuration was studied. Data presented shows that mean wavelength variations with pump power can be reduced to - 9 ppm/mW for selected pump powers by using an Er-doped fiber filter. And the total mean wavelength instability of the fiber source is less than 33 ppm (peak-to-peak) over the - 40℃ to 60℃. The bandwidth reaches 17 nm. The pump power is 55 mW at 974.2 nm and the output power reaches 5.83 mW with 5- m Er- doped fiber.
