Dissipative nonlinear wave dynamics have been investigated extensively in mode-locked lasers with single transverse mode, whereas there are few studies related to three-dimensional nonlinear dynamics within lasers. Recently, spatiotemporal mode locking (STML) was proposed in lasers with small modal (i.e., transverse-mode) dispersion, which has been considered to be critical for achieving STML in those cavities because the small dispersion can be easily balanced. Here, we demonstrate that STML…

Multimode Mamyshev oscillator.
TLDR
This work represents a first, to the best of the knowledge, exploration of STML in an oscillator with a Mamyshev saturable absorber, and indicates that spatiotemporal mode locking (STML) is enabled by nonlinear intermodal interactions and spatial filtering, along with the MamYShev mechanism.
Modal dynamics in multimode optical fibers: an attractor of high-order modes.
TLDR
By employing the Lyapunov exponent, it is proved that the threshold of the HOMs-attractor is consistent with the transition point of the energy flow which indicates the Homs-attracotr acts as a "valve" in the modal energy flow.

Spatiotemporal mode-locking in multimode fiber lasers
TLDR
It is shown that modal and chromatic dispersions in fiber lasers can be counteracted by strong spatial and spectral filtering, which allows locking of multiple transverse and longitudinal modes to create ultrashort pulses with a variety of spatiotemporal profiles.

TLDR
Numerical simulations are conducted to investigate the nonlinear dynamics of multi-pulsing in multimode fiber lasers, and the influences of cavity parameters on the spatiotemporal outputs agree with the experimental observations qualitatively.

TLDR
By taper cut-back, it is observed that the dissipative landscape, i.e., a non-monotonic variation of the average beam power along the MMF, leads to modal transitions of self-cleaned beams along the taper length.
