Spatiotemporal dissipative soliton resonances in multimode fiber lasers

Bo Fu, Haoye Qin, Xuchen Wang, Hao Ouyang, Gang Wang

Spatiotemporal mode-locking in multimode fiber lasers is intriguing for the complex nonlinear dynamics and the increase of theoretical energy limit. In this paper, we enrich spatiotemporal mode-locking with dissipative soliton resonances, a kind of soliton ...
