Self-pulsing dynamics in a cavity soliton laser [PDF]

, 2010
The dynamics of a broad-area vertical-cavity surface-emitting laser (VCSEL) with frequency-selective feedback supporting bistable spatial solitons is analyzed experimentally and theoretically. The transient dynamics of a switch-on of a soliton induced by

Multi-megawatt, self-seeded Mamyshev oscillator

, 2018
We demonstrate a fiber oscillator that achieves 3 MW peak power, is easily started and is environmentally stable. The Mamyshev oscillator delivers 190-nJ pulses that can be compressed externally to 35 fs duration.

Optical Lattice Trap for Kerr Solitons

, 2017
We show theoretically and numerically that dichromatic pumping of a nonlinear microresonator by two continuous wave coherent optical pumps creates an optical lattice trap that results in the localization of intra-cavity Kerr solitons with soliton ...

Buildup and Real-Time Control of Spatiotemporal Nonlinear Dynamics

Ultrafast Science
Ultrafast multimode fiber lasers enable the high-dimensional control of pulses, which can generate spatiotemporal mode-locking with high peak power and multimode Q-switching with large pulse energy.

Streamwise forced oscillations of circular and square cylinders [PDF]

, 2012
The modification of a cylinder wake by streamwise oscillation of the cylinder at the vortex shedding frequency of the unperturbed cylinder is reported. Recent numerical simulations [J. S. Leontini, D. Lo Jacono, and M. C.

Mode locking and spatiotemporal chaos in periodically driven Gunn diodes [PDF]

Physical Review B, 1990
Numerical simulation is applied to study the highly nonlinear-dynamic phenomena that can arise in Gunn diodes by interaction between the internally generated domain mode and an external microwave signal. By adjusting the time of domain formation and the speed of propagation, the internal oscillation entrains with the external signal.

Genetic-Algorithm-Driven Intelligent Spatiotemporal Mode-Locking in All-Fiber Laser with Hysteresis

Photonics
We demonstrate a robust intelligent spatiotemporal mode-locked fiber laser with large modal dispersion, based on the nonlinear polarization rotation mechanism and an electric polarization controller (EPC).

Resonance and frequency-locking phenomena in spatially extended phytoplankton-zooplankton system with additive noise and periodic forces

, 2007
In this paper, we present a spatial version of phytoplankton-zooplankton model that includes some important factors such as external periodic forces, noise, and diffusion processes.

Spatiotemporal Wavevector Dynamics in Transverse Mode-Locked Beams

2025 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)
The phase-locking of transverse higher-order resonator modes results in a beam with rapidly oscillating spatial intensity profile. To complete the description of such transverse mode-locked (TML) beams, their spatiotemporal phase dynamics are explored in this work.

Multiple-soliton in spatiotemporal mode-locked multimode fiber lasers

Optics Express, 2019
Experimental observations of spatiotemporal mode-locked multiple-soliton, including harmonic mode locking and multiple pulses, in multimode fiber (MMF) lasers are reported. Numerical simulations are conducted to investigate the nonlinear dynamics of multi-pulsing.
