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 …

High‐power laser sources are widely used in industrial precision processing and act as a
new platform for strong‐field physics research using peak power over petawatt. This review …

In recent years, additive manufacturing, also known as three-dimensional (3D) printing, has
emerged as an environmentally friendly green manufacturing technology which brings great …

The fiber laser, with its humble beginning in the late 1980s, has undergone tremendous
development in the past decade or so, transforming itself from a research curiosity to a major …

In this paper, we report a high power single frequency 1030 nm fiber laser with near-
diffraction-limited beam quality based on a polarization-maintaining tapered Yb-doped fiber …

We demonstrate that the strong 4-level Yb emission in a fiber laser can be almost completely
suppressed in an Yb all-solid double-clad photonic bandgap fiber, resulting in highly …

High-power fiber lasers have experienced a dramatic development over the last decade.
Further increasing the output power needs an upscaling of the fiber mode area, while …

In this paper, we report the mode area scaling of a rare-earth doped step index fiber by
using low numerical aperture. Numerical simulations show the possibility of achieving an …

Specialty fibers such as chirally-coupled-core fibers show a high potential for further power
scaling of single-frequency fiber amplifiers. For the first time, we demonstrate a spliceless all …

Glass optical fibers have reached a scale and commercial maturity that few, if any, other
material and form can claim. Furthermore, optical fibers not only enable a remarkably broad …
