Yu Chen,Man Wu,Pinghua Tang,Shuqing Chen,Juan Du,Guobao Jiang,Ying Li,Chujun Zhao,Han Zhang,Shuangchun Wen +9 more
TL;DR: In this article, the formation of various multi-soliton patterns and noise-like (NL) pulses in an erbium-doped fiber laser passively mode-locked by a new type of saturable absorber: topological insulator.
High-power and highly efficient operation of wavelength-tunable Raman fiber lasers based on volume Bragg gratings
TL;DR: Highly efficient and high-power operation of Raman fiber lasers in fixed-wavelength and wavelength-tunable cavity configurations based on a graded-index multimode fiber is reported.

TL;DR: In this paper, it was demonstrated that a topological insulator can modulate the operation of a bulk solid-state laser by taking advantage of its saturable absorption, which is potentially attractive as broadband pulsed modulators for the generation of short and ultrashort pulses in bulk solid state lasers, in addition to other promising applications in physics and computing.
Correlation between geometric parametric instability sidebands in graded-index multimode fibers
TL;DR: In this paper, the correlation in energy between the well-separated spectral sidebands through both the scattergrams and the frequency-dependent energy correlation map was investigated and it was shown that conjugate couples are highly correlated while cross-combinations exhibit a very poor degree of correlation.
