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 …

In this paper, we summarize the fundamental properties and review the latest developments
in high power fiber lasers. The review is focused primarily on the most common fiber laser …

Fibre lasers are now associated with high average powers and very high beam qualities.
Both these characteristics are required by many industrial, defence and scientific …

The temporal behavior of mode instabilities in active large mode area fibers is
experimentally investigated in detail. Thus, apart from the onset threshold of mode …

Transverse mode instability (TMI) is compared to thermal lensing (TL) power threshold and
used to derive power scaling limits in high-power fiber amplifiers. The TMI power threshold …

We present a dynamic model of thermal modal instability in large mode area fiber amplifiers.
This model allows the pump and signal optical intensity distributions to apply a time-varying …

We present comprehensive theoretical study of mode instability with a universal model for
the first time, which includes quantitative study on the various influence factors and …

We present a simple theoretical model of transverse mode instability in high-power rare-
earth doped fiber amplifiers. The model shows that efficient power transfer between the …

The threshold-like onset of mode instabilities is currently the main limitation for the scaling of
the average output power of fiber laser systems with diffraction limited beam quality. In this …

In this paper we present a simple model to predict the behavior of the transversal mode
instability threshold when different parameters of a fiber amplifier system are changed. The …
