In recent years, machine learning, especially various deep neural networks, as an emerging
technique for data analysis and processing, has brought novel insights into the development …

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 …

A new measurement technique, capable of quantifying the number and type of modes
propagating in large-mode-area fibers is both proposed and demonstrated. The …

The description of optical fields in terms of their eigenmodes is an intuitive approach for
beam characterization. However, there is a lack of unambiguous, pure experimental …

We have demonstrated a high-power and high-efficiency erbium: ytterbium (Er: Yb) codoped
fiber laser that produces 297 W of continuous-wave output at 1567 nm. The slope efficiency …

In this paper, we report the use of a 3-meter low-loss anti-resonant hollow-core fiber (AR-
HCF) to deliver up to 300 W continuous-wave laser power at 1080 nm wavelength from a …

We propose a novel approach of making large effective area laser fiber with higher
threshold for the stimulated Brillouin scattering (SBS) using Al/Ge co-doping in the fiber core …

Spatially and spectrally resolved imaging of mode content in fibers, or more simply, S 2
imaging, is a new measurement technique for analyzing the mode content of large-mode …

In this paper, we summarize the fundamental properties and review the latest developments
in high power ytterbium-doped fiber (YDF) lasers. The review is focused primarily on the …

Today a specific attention has been paid to look into the modal characteristics of the high-
power laser beam. And the instantaneous monitoring and analyzing on modal content via …
