Spatiotemporal mode-locking and dissipative solitons in multimode fiber lasers [PDF]
Light: Science & Applications, 2023 AbstractMultimode fiber (MMF) lasers are emerging as a remarkable testbed to study nonlinear spatiotemporal physics with potential applications spanning from high energy pulse generation, precision measurement to nonlinear microscopy. The underlying mechanism for the generation of ultrashort pulses, which can be understood as a spatiotempoal ...

Synthesized spatiotemporal mode-locking and photonic flywheel in multimode mesoresonators [PDF]
Nature Communications, 2022 Abstract Dissipative Kerr soliton (DKS) frequency combs—also known as microcombs—have arguably created a new field in cavity nonlinear photonics, with a strong cross-fertilization between theoretical, experimental, and technological research.

A High-Energy Wide-Spectrum Spatiotemporal Mode-Locked Fiber Laser [PDF]
Micromachines, 2023 In this article, we demonstrate a high-energy, wide-spectrum, spatiotemporal mode-locked (STML) fiber laser. Unlike traditional single-mode fiber lasers, STML fiber lasers theoretically enable mode-locking with various combinations of transverse modes.

Spatiotemporally mode-locked soliton fiber laser at 2.8 μm
High Power Laser Science and Engineering, 2023 AbstractSpatiotemporal 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.

Multi-Wavelength Spatiotemporal Mode-Locked Fiber Laser at 1.55 μm
Photonics, 2022 We propose and demonstrate an effective and simple multi-wavelength spatiotemporal mode-locked (STML) laser. The laser introduces a multimode interference (MMI) effect using the core diameter mismatch of the fibers, thus enabling simultaneous mode-locking at multiple wavelengths.

Spatiotemporal mode locking in quadratic nonlinear media [PDF]
Physical Review E, 2020 A new theoretical model is developed to characterize spatio-temporal mode-locking (ML) in quadratic nonlinear media. The model is based on the two-dimensional nonlinear Schr dinger equation with coupling to a mean term (NLSM) and constructed as an extension of the master mode-locking model. It is numerically demonstrated that there exists steady state

Mechanisms of spatiotemporal mode-locking [PDF]
Nature Physics, 2020 Mode-locking is a process in which different modes of an optical resonator establish, through nonlinear interactions, stable synchronization. This self-organization underlies light sources that enable many modern scientific applications, such as ultrafast and high-field optics and frequency combs.

Spatiotemporal Mode-Locking as Multidimensional Optimization [PDF]
Conference on Lasers and Electro-Optics, 2019 We outline a theoretical framework to understand the multitude of new mode-locked states possible in multi-transverse mode resonators. Full-3D measurements of mode-locked states comprising roughly 30 million modes agree with theoretical expectations.
