Our work centres on mode-locked fiber lasers — how mode locking starts, stabilises and survives long-term operation, and how far the repetition rate of a fiber oscillator can be pushed. We are now extending that work toward optical frequency combs. 我们的工作以锁模光纤激光器为中心：锁模如何起振、如何稳定、如何长期可靠运行，以及光纤振荡器的重复频率能推到多高。目前正把这条线延伸到光频梳。
Mode-locked fiber lasers: how mode locking starts, stabilises, and holds up over long runs. We work across NALM and NPR cavities as well as material saturable absorbers. 锁模光纤激光器：锁模如何起振、如何稳定、如何长期可靠运行。腔型上涵盖 NALM 与 NPR，也包括材料可饱和吸收体锁模。
Pushing the fundamental repetition rate of fiber oscillators upward: short-cavity design, matching gain against dispersion, and the characterisation that goes with it. 把光纤振荡器的基频重复频率往上推：短腔设计、增益与色散的匹配，以及随之而来的表征方法。
A direction we are moving into: extending the group's existing ultrafast fiber sources toward low-noise frequency combs. Early stage. 正在拓展的方向：把课题组已有的超快光纤光源延伸到低噪声光频梳，目前处于起步阶段。
Nonlinear optics in fiber: the interplay of dispersion and nonlinearity, pulse shaping and supercontinuum generation, and how these feed back into cavity dynamics. 光纤中的非线性光学：色散与非线性的相互作用、脉冲整形与超连续谱产生，以及它们对腔内动力学的反馈。

Updates from Web of Science and our own literature sweeps, ranked by relevance to the group and labelled peer-reviewed / early access / preprint. Student ID and password required. 汇总 Web of Science 与课题组自建检索的更新，按与研究方向的相关度分级，并标注同行评议 / early access / 预印本。需使用学号和密码登录。
Journal articles and early access first, then publisher feeds; arXiv preprints only as a supplement. General-optics papers with weak relevance to the group are excluded. 优先正式期刊与 early access，其次出版社最新文章，arXiv 预印本仅作补充；与课题组方向关联弱的泛光学文章不予收录。
A curated bibliography is being assembled. This section will link to journal articles, technical notes and datasets as they become available. 论文清单正在整理。本栏目将陆续给出期刊论文、技术笔记与数据集的链接。
