Artificial saturable absorbers (SA) are nonlinear optical devices widely employed in mode‐
locked lasers. Among the artificial SAs are nonlinear polarization evolution (NPE) and …

We review the research status of the mechanism and technology of all-fiber mode-locked
ultrafast laser with multimode fiber based saturable absorber. Using novel all-fiber structured …

We demonstrate experimentally a double-clad Er: Yb co-doped dual amplifier passive mode-
locked figure-of-eight fiber laser that generates high energy, width, and amplitude tunable …

The first demonstration of a compact all-fiber figure-9 double-clad erbium-ytterbium laser
working in the dissipative soliton resonance (DSR) regime is presented. Mode-locking was …

Fundamental and harmonic mode-locking in the dissipative soliton resonance (DSR) regime
is experimentally investigated in a net-normal-dispersion Er/Yb co-doped fiber laser based …

In this paper, the phenomenon of reverse saturable absorption of offset-spliced graded
index multimode fibers (OS-GIMF) is revealed. And based on that, the stable square-shaped …

Due to the quantization of the pulse energy in fiber lasers, it is challenging to find effective
ways to increase the pulse energy directly from a fiber laser oscillator. One efficient and …

We report an experimental study of passive harmonic mode-locking in an all-fiber switchable
dual-wavelength Er/Yb double-clad laser. The proposed scheme supports single-and dual …

We report on the first demonstration of dual-wavelength square-wave pulses in a thulium-
doped fiber laser. Under appropriate cavity parameters, dual-wavelength dissipative soliton …

Emission of an all-fiber, Dissipative Soliton Resonance (DSR) mode-locked, Double-Clad
(DC), Erbium-Ytterbium (Er: Yb) laser configuration is investigated under several different …
