Nonlinear beam self-maintaining effect in graded-index multimode fiber
Baofu Zhang, Shanchao Ma, Qiurun He +4
Multimode fiber systems are desirable for industrial and scientific applications. As an interesting effect for the laser beam propagation in a multimode fiber, nonlinear Kerr beam…

A wavelength-tunable mode-locked Yb-doped fiber laser based on nonlinear Kerr beam clean-up effect
Shanchao Ma, Baofu Zhang, Qiurun He +2
We demonstrate a novel approach to achieve wavelength-tunable ultrashort pulses from an all-fiber mode-locked laser with a saturable absorber based on nonlinear Kerr beam clean-up…

All-fiber mode-locked ytterbium-doped fiber laser with a saturable absorber based on nonlinear Kerr beam cleanup effect
Baofu Zhang, Shanchao Ma, Sihua Lu +4
We theoretically and experimentally demonstrate a novel mode-locked ytterbium-doped fiber laser with a saturable absorber based on nonlinear Kerr beam cleanup effect. The saturable…
