Mode-locking is a process in which different modes of an optical resonator establish stable
synchronization through non-linear interactions. This self-organization underlies light …

Ultrafast fiber lasers have the potential to make applications of ultrashort pulses widespread–
techniques not only for scientists, but also for doctors, manufacturing engineers, and more …

Building on the scientific understanding and technological infrastructure of single-mode
fibers, multimode fibers are being explored as a means of adding new degrees of freedom to …

In this article, we review recent advances in the technology of writing fiber Bragg gratings
(FBGs) in selected cores of multicore fibers (MCFs) by using femtosecond laser pulses. The …

A mode-locked all-fiber laser based on the nonlinear multimode interference (NL-MMI) effect
of the graded-index multimode fiber (GIMF) is proposed and demonstrated. The saturable …

Direct ultrafast laser processing is nowadays considered the most flexible technique
allowing to generate complex 3D optical functions in bulk glasses. The fact that the built-in …

A novel mode-locking method based on the nonlinear multimode interference in the
stretched graded-index multimode optical fiber (GIMF) is proposed in this Letter. The simple …

Ultrashort pulse generation at the short-wave infrared (SWIR) wavelength ranges from 1.6 to
2.5 μ m and together with benefits of the all-fiber design has transformed lasers into an …

An Er-doped mode-locked fiber laser with a saturable absorber based on single mode-
graded index multimode-single mode fiber (SMF-GIMF-SMF) with inner micro-cavity is …

We experimentally demonstrate for the first time, to the best of our knowledge, an all-fiber
passively mode-locked laser operation based on the nonlinear multimode interference of …
