摘要：
Intermodal dispersion is the main problem restricting the establishment and stability of spatiotemporal mode-locking (STML) in the anomalous dispersion region. In the experiment, we employ the multimode Er-Yb double-clad fiber to carry out the multimode operation as a gain medium. The nonlinear multimode interference is used to enhance the mode coupling and spatial filtering in the cavity, achieve the purpose of suppressing the intermodal dispersion, and successfully realize the 1550 nm spatiotemporal noise-like solitons of Mamyshev oscillator based on the multimode gain fiber. The noise-like spatiotemporal soliton pulse energy reaches similar to 171.29 nJ, and the corresponding peak power is similar to 30.32 kW. The intermodal dispersion suppression based on nonlinear multimode interference performance makes this laser an attractive tool for practical applications.
