Self-cleaning effect in an all-fiber spatiotemporal mode-locked laser based on graded-index multimode fiber
Chuansheng Dai, Zhipeng Dong, Jiaqiang Lin +4
We demonstrate an all-fiber spatiotemporal mode-locked laser based on graded-index multimode fiber. Due to the high damage threshold of graded-index multimode fiber devices, the ou…
Generation mode-locked square-wave pulse based on reverse saturable absorption effect in graded index multimode fiber
Zhipeng Dong, Shu jie Li, Jiaqiang Lin +5
We firstly report mode-locked square-wave pulse in Yb-doped fiber laser based on graded index multimode fiber of reverse suturable absorption. By adjusting the pump power, the widt…
Passively Q-switching cylindrical vector beam fiber laser operating in high-order mode
Hongxun Li, Ke Yan, Yimin Zhang +9
We experimentally demonstrate a linear-cavity all-fiber passively Q-switching cylindrical vector beam (CVB) laser operating in high-order mode. This CVB fiber laser operates withou…
Mode-locked fiber laser with offset splicing between two multimode fibers as a saturable absorber
Zhipeng Dong, Shujie Li, Peijun Yao +2
A novel mode-locked fiber laser based on offset splicing technology between two kinds of graded index multimode fibers is proposed and experimentally demonstrated. The offset splic…
