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 success of high-power fiber lasers is fueled by maturation of active and passive fibers,
combined with the availability of high-power fiber-based components. In this contribution, we …

Fiber laser technology has been demonstrated as a versatile and reliable approach to laser
source manufacturing with a wide range of applicability in various fields ranging from …

A comprehensive account of the latest developments and applications in this rapidly
developing field, covering a wide range of topics, such as power scaling and short pulse …

We present a birefringent Yb-doped tapered double-clad fiber with a record core diameter of
96 µm. An impressive gain of over 38 dB was demonstrated for linearly polarized CW and …

We have experimentally studied fundamental mode propagation in few meters long,
adiabatically tapered step-index fibers with high numerical aperture, core diameter up to 117 …

Thanks to the advantage of balancing nonlinear effects and transverse mode instability, vary
core diameter active fiber (VCAF) has been widely used in high power ytterbium-doped fiber …

A concise and effective model based on coupled mode theory to describe mode evolution in
long tapered active fiber is presented in this manuscript. The mode coupling due to variation …

We present a CW single-frequency laser at 1062 nm (linewidth< 3 MHz) with 160 W of total
output power based on a two stage fiber amplifier. A GTWave fiber is used for the first stage …

High-energy Q-switched master oscillator power amplifier systems based on rod-type 4?×?
4 multicore fibers are demonstrated, achieving energy up to 49 mJ in ns-class pulses. A …
