由于数值孔径有限，单模光纤中会发生纵向和横向受激布里渊散射。我们讨论了纤维结构的作用，并提出了一个考虑这两种效应的相干模型。我们通过实验和数值证明，在某些情况下，微扰包层布里渊散射 (CBS) 会严重影响 SBS 布里渊光纤激光器的动力学。提出了长光纤布里渊环激光器的新动态机制，包括稳定的调制脉冲序列。
Due to their finite numerical aperture, both longitudinal and transverse stimulated Brillouin scattering can occur in single-mode fibers. We discuss the role of the fiber structure and propose a coherent model accounting for both effects. We show experimentally and numerically that, in some cases, the perturbative cladding Brillouin scattering (CBS) can severely affect the dynamics of SBS Brillouin fiber lasers. New dynamical regimes of long-fiber Brillouin ring lasers are presented, including stable trains of modulated pulses.
