In this brief review we consider the main factors determining the oscillation spectral range of
cladding‐pumped ytterbium‐doped fiber lasers (YDFLs) and the results obtained for lasers …

Power scaling of fiber lasers is challenged by several factors, such as the brightness of the
pump source, the nonlinear effect, modal instability, and so on. Pumping active fibers with …

We present review on recent progress on high power Yb-doped fiber laser in a variety of
oscillation spectral ranges. According to Kurkov (Laser Phys. Lett. 2006), the oscillation …

We report experimental results showing novel features in photo‐darkening and photo‐
bleaching of a heavily‐doped Ytterbium silica fiber exposed to in‐core 977‐nm and 543‐nm …

Ytterbium-doped solid-core photonic bandgap fiber amplifiers operating at the long-
wavelength edge of the ytterbium gain band are reported. The low-loss bandgap …

We report a tunability study of a mode-locked Yb-doped self-similar fiber laser. The center
wavelength is tunable from 1030 to 1100 nm without losing mode locking by adjusting a …

We achieved a 0.2 nm linewidth output at 1178nm with powers up to 6.4 W in a linear 80m
Bismuth-doped fiber cavity pumped by a 55W Yb fibre laser. The potential of frequency …

For the first time we have suggested and realized passive Q-switched Yb-doped fiber laser
with a saturable absorber based on Ho-doped fiber laser. The pulse duration was of 250 ns …

An ytterbium-doped photonic bandgap fiber amplifier operating at the long wavelength edge
of the ytterbium gain band is investigated for high power amplification. The spectral filtering …

We have made and studied a set of the fiber lasers based on Ho‐doped fiber with high
concentration of the active ions. For the first time the spectral efficiency in a range of 2.02 …
