Journal ArticleDOI
Geometrical description of the onset of multi-pulsing in mode-locked laser cavities
TL;DR: In this article, a simple iterative model is introduced quantifying the interaction of saturable gain and nonlinear loss in a mode-locked laser cavity, which completely characterizes the generic multi-pulsing instability observed in experiments.
Journal ArticleDOI
Actively mode-locked all fiber laser with cylindrical vector beam output
TL;DR: Through adjusting the polarization state in the laser cavity, both radially and azimuthally polarized beams have been obtained with high mode purity.
Journal ArticleDOI

TL;DR: A novel all-fiber laser generating cylindrical vector beams with high slope efficiency and low threshold is demonstrated by introducing a long-period fiber grating into the laser cavity by introducing the TM-FBG.
Journal ArticleDOI
Investigating the influence of a weak continuous-wave-trigger on picosecond supercontinuum generation.
TL;DR: By controlling the CW-trigger wavelengths, the rogue solitons emerged in SC generation can exhibit high-degree of temporal coherence and pulse-to-pulse intensity stability.
Journal ArticleDOI
Highly coherent supercontinuum generation with picosecond pulses by using self-similar compression
TL;DR: This paper shows that a 1 ps pump pulse with random noise can be compressed self-similarly down to a pulse width of 53.6 fs with negligible pedestal, and the tolerance of noise level for highly coherent SC generation with picosecond pump pulses can be improved by 5 order of magnitude.
