提出了一种基于反向泵浦-探测技术的级联前向布里渊散射（CFBS）产生方法。前向受激布里渊散射（FSBS）是通过探测光的能量转移到其他声学共振频率而产生的。在390 m长的高度非线性光纤中产生的CFBS频谱具有较高的信噪比（SNR），其声学共振峰的中心频率与理论值一致。此外，信噪比依赖于泵浦/探测功率和CFBS频移依赖于温度进行了研究。
We present a method for generating cascaded forward Brillouin scattering (CFBS) on the basis of a counter-propagated pump-probe technique with backward stimulated Brillouin scattering used as its seed. The CFBS, induced by forward stimulated Brillouin scattering (FSBS), is generated via the energy transfer from the probe light to other acoustic resonance frequencies. The CFBS spectrum generated in a 390-m-long highly nonlinear fiber exhibits a high signal-to-noise ratio (SNR), and the center frequencies of its acoustic resonance peaks agree with theoretical values. In addition, the SNR dependence on pump/probe powers and the CFBS frequency shift dependence on temperature are investigated.
