主 题：dissipative nonlinear locking
摘 要：Multimode fiber(MMF)lasers are emerging as a remarkable testbed to study nonlinear spatiotemporal physics with potential applications spanning from high energy pulse generation,precision measurement to nonlinear microscopy.The underlying mechanism for the generation of ultrashort pulses,which can be understood as a spatiotempoal dissipative soliton(STDS),in the nonlinear multimode resonators is the spatiotemporal mode-locking(STML)with simultaneous synchronization of temporal and spatial modes.In this review,we first introduce the general principles of STML,with an emphasize on the STML dynamics with large intermode dispersion.Then,we present the recent progress of STML,including measurement techniques for STML,exotic nonlinear dynamics of STDS,and mode field engineering in MMF lasers.We conclude by outlining some perspectives that may advance STML in the near future.
