Multimode nonlinear dynamics in spatiotemporal mode-locked anomalous-dispersion lasers

Optics Letters, 2022
Spatiotemporal mode-locking in a laser with anomalous dispersion is investigated. Mode-locked states with varying modal content can be observed, but we find it difficult to observe highly-multimode states. We describe the properties of these mode-locked states and compare them to the results of numerical simulations.

Switchable and spacing tunable dual-wavelength spatiotemporal mode-locked fiber laser

Optics Letters, 2021
We report a switchable and spacing tunable dual-wavelength spatiotemporal mode-locked (STML) laser based on the multimode interference filtering effect in an all-fiber linear cavity. The dual-wavelength STML operations combined with different pulse patterns are achieved.

Spatial self-beam cleaning in spatiotemporally mode-locked fiber lasers

2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2021
In recent years, by exploiting the low modal dispersion of graded-index multimode fibers, spatiotemporal mode-locking was demonstrated in multimode fiber laser cavities [1] . The use of multimode fibers inside the laser cavity is proposed as a new path to achieve high energy and peak power pulses from fiber lasers.

All Few-mode Fiber Spatiotemporal Mode-Locked Figure-eight Laser

Journal of Lightwave Technology, 2021
Spatiotemporal mode-locked (STML) fiber lasers attract great interest owing to their distinctive spatiotemporal characteristics and potential to generate high-energy pulse. Herein, we report an all few-mode fiber figure-eight laser STML by a nonlinear amplifying loop mirror at 1.0 µm.

Self-similar spatiotemporal mode-locked fiber laser (Conference Presentation)

Fiber Lasers XVII: Technology and Systems, 2020
We present the first spatiotemporally mode-locked fiber laser with self-similar pulse evolution, to the best of our knowledge. Our multimode fiber laser produces amplifier similaritons with near-Gaussian beam quality (M2 6) and less chirped pulses than the cavity induced total dispersion are the verifications of the spatiotemporal self-similar pulse ...

Pulse dynamics in spatiotemporal mode-locked multimode fiber lasers

2018 Asia Communications and Photonics Conference (ACP), 2018
We report on the experimental observation of multiple-soliton (harmonic mode-locking, multiple pulses, etc.) and period-timing bifurcations in spatiotemporal mode-locked multimode fiber lasers. The transition of operation states, from uniformity output to period-timing bifurcations, then to chaos is also observed.

Spatiotemporal mode-locking: what it is, and different types

Advanced Photonics 2018 (BGPP, IPR, NP, NOMA, Sensors, Networks, SPPCom, SOF), 2018
We describe, in general terms, what spatiotemporal mode-locking is and how it happens. Then we describe several recent new developments, including qualitatively distinct kinds of 3D pulses and mode-locking physics.

Spatial Beam Cleaning in Ytterbium Spatiotemporal Mode-Locked Fiber Laser

2025 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)
Spatiotemporal mode-locked (STML) lasers based on multimode fibers enable the simultaneous locking of longitudinal and transverse laser modes [1]. These light sources permit scaling up the generated pulse energy and exhibit complex spatiotemporal dynamics [4].
