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. In the period-doubling state, it is observed that the pulse train modulation varies with the transverse-mode, and the output beam profile fluctuates rapidly and…

Buildup dynamics of multiple solitons in spatiotemporal mode-locked fiber lasers
Spatiotemporal mode locking is a nonlinear process of multimode soliton self-organization. Here the real-time buildup dynamics of the multiple solitons in a spatiotemporal mode-locked multimode fiber


Spatiotemporal Mode-Locking in Lasers with Large Modal Dispersion.
It is demonstrated that STML can also be achieved in multimode lasers with much larger modal dispersion, where it is found that the intracavity saturable absorber plays an important role for counteracting the large modal Dispersion.
Observation of period-doubling bifurcations in a femtosecond fiber soliton laser with dispersion management cavity.
This experimental result shows that the nonlinear propagation of soliton pulses in the laser cavity is an intrinsic dynamic process, which follows the universal laws of the non linear dynamic systems.
Mechanism for period-doubling bifurcation in a semiconductor laser subject to optical injection.
The single-mode rate equations for a semiconductor laser subject to optical injection are investigated analytically and the optical power spectrum is computed utilizing the perturbation solutions of the phase equation before and after the period-doubling transition.
Single-mode output by controlling the spatiotemporal nonlinearities in mode-locked femtosecond multimode fiber lasers
Abstract. The performance of fiber mode-locked lasers is limited due to the high nonlinearity induced by the spatial confinement of the single-mode fiber core. To massively increase the pulse energy
Nonlinear Dynamics of Mode-locking Optical Fiber Ring Lasers
We consider a model of a mode-locked fiber ring laser for which the evolution of a propagating pulse in a birefringent optical fiber is periodically perturbed by rotation of the polarization state
Mechanisms of spatiotemporal mode-locking
Mode-locking is a process in which different modes of an optical resonator establish stable synchronization through non-linear interactions. This self-organization underlies light sources that enable
Multiple-soliton in spatiotemporal mode-locked multimode fiber lasers.
Numerical simulations are conducted to investigate the nonlinear dynamics of multi-pulsing in multimode fiber lasers, and the influences of cavity parameters on the spatiotemporal outputs agree with the experimental observations qualitatively.
Spatiotemporal mode-locking in multimode fiber lasers
It is shown that modal and chromatic dispersions in fiber lasers can be counteracted by strong spatial and spectral filtering, which allows locking of multiple transverse and longitudinal modes to create ultrashort pulses with a variety of spatiotemporal profiles.
