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…
An all-fiber laser oscillating directly at single TE01 mode through ring-core fibers
Yimin Zhang, Hongxun Li, Chuansheng Dai +7
Cylindrical vector beams (CVBs) have a wide range of applications owing to their particular polarization characteristics and optical field distributions. For the first time, an azi…
Yb-doped all fiber picosecond laser based on grade-index multimode fiber with microcavity
Zhipeng Dong, Shujie Li, Ruishan Chen +4
We demonstrate an all-fiber mode-locked laser at all-normal dispersion with a saturable absorber, which is based on a section of grade-index multimode fiber with inner microcavity…
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…
