摘要
实验研究了单频单模保偏掺Yb光纤放大器中的受激布里渊散射(SBS)效应。采用前向抽运的两级级联掺Yb光纤放大器，研究了保偏光纤放大器中的受激布里渊散射的光谱变化特性。理论计算的单模光纤的布里渊频移和SBS阈值与实验测试的结果进行了比较。在光纤放大器前后两端观察到多级次的斯托克斯(Stokes)谱线和多级的反斯托克斯(anti-Stokes)谱线，这是由级联受激布里渊散射和四波混频过程产生的。
Abstract
Experimental results for the stimulated Brillouin scattering (SBS) in the single-frequency, single-mode, linearly polarized ytterbium-doped fiber amplifier are reported. The fiber amplifier configuration comprises of two-stage master oscillator power amplifier with co-propagating signal and pump light. The evolution of SBS spectra is investigated in the experiments. Multiorder Stokes and anti-Stokes scattering can be observed in the forward and backward directions of the fiber amplifier, which generate through cascaded SBS and four-wave mixing process.
