| 摘 要： | 讨论了背向自发Raman散射脉冲在自生分布式G652光纤Raman放大器中传输的增益特性。实验发现，反Stokes Raman（ASR）和Stokes Raman（SR）自生分布式脉冲光纤Raman放大器的阈值抽运峰值功率是25．4W和18．0W。在入射功率为52W时，ASR和SR的增益分别为5．0dB和8．6dB。放大的反Stokes和Stokes背向自发Raman散射光时域反射（OTDR）曲线上放大的阈值时间位置随激发功率的增高前移并具有规律性。放大的ASR背向自发散射强度受光纤温度调制，具有温度效应，已应用于远程分布光纤Raman温度传感器系统。

| Abstract: | The gain characteristics of G652 optical fiber backward spontaneous Raman scattering pulse in the self-generating distributed G652 fiber Raman amplifier are discussed.The threshold pump powers of anti-Stokes Raman(ASR) and Stokes Raman(SR) in the self-generating distributed G652 fiber Raman amplifier are 25.4 W and 18 W respectively.When the excited power is 52 W,the gain of ASR and SR are 5.0 dB and 8.6 dB respectively.In optical time domain reflection(OTDR) curve of amplified anti-Stokes and Stokes spontaneous Raman scattering signal the threshold time changes with pump power,and will move forward with the increase pump power.Amplified anti-Stokes spontaneous Raman scattering signal has the temperature effect,and this effect has been applied to long distance distributed optical fiber temperature sensor system. |
