This work presents a review on the effect of transverse mode instability in high-power fiber
laser systems and the corresponding investigations led worldwide over the past decade …

We present the first experimental realization of a new mitigation strategy for TMI based on
controlling the phase shift between the modal intensity pattern and the thermally induced …

A novel double-layer all-solid anti-resonant fiber (DL-AAF) is proposed to develop large
mode area (LMA) fiber for high-power fiber laser applications. Single-mode property and …

Yb-doped double-cladding photonic crystal fibers are one of the key enabling factors for the
development of high-power fiber lasers, due to their capability to provide a very large-mode …

We report on the first, to the best of our knowledge, implementation of a fluorine co-doped
large-mode-area REPUSIL fiber for high peak power amplification in an ultrashort-pulse …

The first demonstration of a 40 μm core homogeneously ytterbium-doped fully aperiodic
large-pitch fiber laser, to the best of our knowledge, is reported here. In this concept, the …

To prevent the thermally induced spatial beam degradation occurring in high-power fiber
lasers and amplifiers, index-depressed core “fully aperiodic large-pitch fibers”(FA-LPFs) …

A polarization-maintaining large-mode-area solid-core anti-resonant fiber is investigated in
this work with double-layer anti-resonant elements for improved capability on fundamental …

Optical fiber-based spectroscopy sensors are widely used for industrial and biomedical
applications. They normally consist of at least one excitation fiber and one collection fiber …

We report here on an experimental investigation of the temporal behavior of transverse
mode instabilities into “fully aperiodic large-pitch fibers”(FA-LPFs) operated in high-power …
