在掺铒光纤激光器中，采用合适的高非线性光纤段，实现了拉曼散射辅助的类噪声脉冲（NLP）产生。获得了具有203 nm 3 dB带宽的宽带频谱，据我们所知，这是NLP实现的最宽带宽。宽带操作是定制腔设计的结果，其优化了包括拉曼散射效应的各种效应以最大化NLP的带宽。进一步拓宽NLP光谱高达294 nm，实现了通过使用光谱过滤腔外的偏振分束器。
Raman-scattering-assisted noise-like pulse (NLP) generation was achieved by using an appropriate segment of high nonlinearity fiber in an erbium-doped fiber laser. Broadband spectrum with 203 nm 3-dB bandwidth was obtained, which, to the best of our knowledge, is the broadest bandwidth achieved for NLPs. The broadband operation is the result of tailored cavity design, which optimizes various effects including the Raman scattering effect to maximize the bandwidth of NLPs. Further broadening the NLP spectrum up to 294 nm was achieved by using spectral filtering outside the cavity with a polarization beam splitter.
