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…
