Period-doubling bifurcation in spatiotemporal mode-locked lasers
Period-doubling bifurcation is a universal dynamic of nonlinear systems, which has been extensively investigated in laser systems with a single transverse mode. This study presents an experimental observation and theoretical investigation of the period-doubling bifurcation in spatiotemporal mode-locked (STML) multimode fiber lasers.

Topological Spatiotemporal Mode-Locked Lasers
Abstract Achieving robust high-dimensional solitons both in optics and Bose-Einstein condensates remains a great challenge, due to the unpredictable high-order perturbations. Here, we propose and demonstrate a novel topological spatiotemporal mode-locked fiber laser empowered by mode-division multiplexing, for precisely controlling of ...

Investigation of spatiotemporal mode-locked fiber lasers with hybrid dispersion
In this work, by controlling the magnitude of the fourth-order dispersion (FOD) values introduced in the multimode fiber mode-locked laser system, the influence of hybrid dispersion (mainly second-order and FOD) on the spatiotemporal mode-locked fiber laser was studied.

A new method for the determination of the locking range of oscillators [PDF]
A time-domain method for the determination of the injection-locking range of oscillators is presented. The method involves three time dimensions: the first and the second are warped time scales used for the free-running frequency and the external ...

Spatiotemporal dynamics of a passively mode-locked Nd:GdVO4laser
By examining beam patterns, temporal pulse forms, and radio-frequency spectra as functions of resonator configuration and pump power, we found that a passively mode-locked Nd:GdVO4 laser exhibited four main regimes of operation that were single-transverse-mode Q-switched mode locking (QSML), single-transverse-mode continuous-wave mode locking (CWML ...

The link between coherence echoes and mode locking [PDF]
We investigate the appearance of sharp pulses in the mean field of Kuramoto-type globally- coupled phase oscillator systems. In systems with exactly equidistant natural frequencies self- organized periodic pulsations of the mean field, called mode ...

Energy-managed spatiotemporal mode-locked fiber lasers
This paper proposes an energy-managed spatiotemporal mode-locked (STML) fiber laser, in which the potential enhancement in soliton energy and intriguing spatiotemporal dynamics of solitons are explored. In STML lasers, counteracting modal dispersion is crucial for achieving stable STML solitons. Here, we demonstrate that the energy-managed mechanism is

Model for passive mode locking in semiconductor lasers
We derive and study a model describing passive mode locking—a set of differential equations with time delay. Unlike classical mode locking models based on the Haus master equation, this model does not assume small gain and loss per cavity round trip ...
