Dynamic Observation of Ultrashort Pulses with Chaotic Features in a Tm-Doped Fiber Laser with a Single Mode Fiber–Grade Index Multimode Fiber–Single Mode Fiber Structure

Dynamic Observation of Ultrashort Pulses with Chaotic Features in a Tm-Doped Fiber Laser with a Single Mode Fiber–Grade Index Multimode Fiber–Single Mode Fiber Structure

In this study, we have demonstrated an ultrafast Tm-doped fiber laser utilizing the nonlinear multimode interference (NL-MMI) effect, with a single mode fiber–grade index multimode fiber–single mode fiber (SMF-GIMF-SMF) structure serving as the saturable absorber (SA). In addition to stable pulses,...
