The first fiber Bragg gratings were accidentally written in a Ge-doped silica fiber using a high
power argon–ion laser [Hill 1978]. Following this first evidence of photosensitivity in optical …

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 demonstrate an experimental study on scaling mode instability (MI) threshold in fiber
amplifiers based on fiber coiling. The experimental results show that coiling the active fiber …

Linearly-polarized (LP) fiber lasers, which could find wide potential applications such as
coherent detection, coherent/spectral beam combining, nonlinear frequency conversion …

We report on an ytterbium-doped single-transverse-mode rod-type photonic crystal fiber that
combines the advantages of low nonlinearity and intrinsic polarization stability. The mode …

A 332 W all-fiber amplifier chain with single frequency and single polarization (average
extinction ratio> 21 dB) is presented based on master oscillator power amplification …

The ability to strip cladding light from double clad fiber (DCF) fibers is required for many
different reasons, one example is to strip unwanted cladding light in fiber lasers and …

We present an investigation on the threshold of thermal-induced mode instability (MI) in
ytterbium-doped polarization-maintaining and non-polarization-maintaining active fibers. By …

Efficient high-power operation of double-clad Er, Yb-doped fiber lasers with fixed-
wavelength and wavelength-tunable resonator configurations using volume Bragg gratings …

In this work, a narrow-linewidth linearly polarized fiber amplifier with a record output power
of 3.2 kW was achieved based on a homemade polarization-maintaining Yb-doped fiber …
