Spatiotemporal Mode-Locking in Lasers with Large Modal Dispersion. [PDF]
Physical Review Letters, 2019 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.

Mechanisms of dual-wavelength dissipative soliton mode-locking in net-normal dispersion fiber lasers
Results in Physics, 2022 Dual-wavelength mode-locked fiber lasers have attracted great attention due to their enormous potential in facilitating dual-comb spectroscopy. However, mechanism for dual-wavelength dissipative soliton mode-locking and the intracavity dynamics are still

Passively Mode-Locked Raman Laser [PDF]
Physical Review Letters, 2010 We report on the observation of a novel mode locked optical comb generated at the Raman offset (Raman comb) in an optically pumped crystalline whispering gallery mode resonator. Mode locking is confirmed via measurement of the radio-frequency beat note produced by the optical comb on a fast photodiode.

Self−Mode−Locked 2−μm GaSb−Based Optically Pumped Semiconductor Disk Laser
Applied Sciences, 2023 We present a mode−locked GaSb−based optically pumped semiconductor disk laser operating at 2 µm based on the self−mode−locked mechanism. Using the delay differential equation model, we discuss the influence of cavity length on the stability of self−mode ...

Interaction of two magnetic micro-chains in a rotating field
AIP Advances, 2020 Interactions between two chains consisted of micro-sized magnetic beads are experimentally investigated. Driven by a rotating field, three distinct modes of magnetic interactions are identified, referred to as chaining, locking and transit.

Spatiotemporally mode-locked soliton fiber laser at 2.8 μm
High Power Laser Science and Engineering, 2023 Spatiotemporal mode-locking creates great opportunity for pulse energy scaling and nonlinear optics research in fiber. Until now, spatiotemporal mode-locking has only been realized in normal-dispersion dissipative soliton and similariton fiber lasers. In
