锁模光纤激光器是超短脉冲的重要来源，其中稳定的脉冲生成是通过周期性幅度和相位演化的平衡来实现的。一系列不同的腔脉冲动力学已经被揭示，这些动力学是由色散和非线性之间的相互作用以及滤波等耗散过程引起的。这导致了许多新颖的操作方式的发现，显着提高了激光性能。在这篇专题综述中，我们总结了迄今为止通过腔色散工程报道的主要稳态脉冲动力学，包括平均孤子、色散管理孤子、耗散孤子、巨啁啾脉冲和相似子。除了典型性能和局限性之外，还描述了每种状态的特征和稳定机制，并得到数值模型的支持。除了考虑其他最新进展（包括自动自调谐腔和基于氟化物光纤的中红外锁模激光器）之外，还讨论了进一步脉冲能量缩放的机会。
Mode-locked fibre lasers are important sources of ultrashort pulses, where stable pulse generation is achieved through a balance of periodic amplitude and phase evolutions. A range of distinct cavity pulse dynamics have been revealed, arising from the interplay between dispersion and nonlinearity in addition to dissipative processes such as filtering. This has led to the discovery of numerous novel operating regimes, offering significantly improved laser performance. In this Topical Review, we summarise the main steady-state pulse dynamics reported to date through cavity dispersion engineering, including average solitons, dispersion-managed solitons, dissipative solitons, giant-chirped pulses and similaritons. Characteristic features and the stabilisation mechanism of each regime are described, supported by numerical modelling, in addition to the typical performance and limitations. Opportunities for further pulse energy scaling are discussed, in addition to considering other recent advances including automated self-tuning cavities and fluoride-fibre-based mid-infrared mode-locked lasers.
