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 …

The transverse mode instability (TMI) has been one of the main limitations for the power
scaling of single mode fiber lasers. In this work, we report a 6 kW single mode monolithic …

We report on a thin-disk laser system with more than 10 kW of output power and a beam
quality of M^ 2= 1.76 at an overall optical-to-optical efficiency of 51%. The system consists of …

In this work, we conduct a detailed experimental study on the impact of signal bandwidth on
the TMI threshold of fiber amplifiers. Both the filtered superfluorescent fiber sources and the …

We present highly robust fiber Bragg gratings (FBGs) in passive large-mode-area fibers for
kilowatt fiber laser systems. The gratings were inscribed directly through the fiber coating …

High-power lasers operating at the 2 μm wavelength domain have gained considerable
interest in recent times owing to their distinct characteristics and versatile applications in the …

The experimental investigation of mode distortion induced by stimulated Raman scattering
(SRS) in a high-power fiber amplifier, which includes the evolutions of optical spectra …

We have demonstrated an industrial 6 kW single-stage end-pumped all-fiber laser oscillator
based on a conventional large mode area ytterbium-doped fiber (YDF) with 30 μm core …

Power scaling based on traditional ytterbium-doped fibers (YDFs) is limited by optical
nonlinear effects and transverse mode instability (TMI) in high-power fiber lasers. Here, we …
