Ytterbium-doped fiber amplifiers
TLDR
The ytterbium-doped fiber amplifier offers a number of attractive features, including a broad-gain bandwidth and a high efficiency, due in large part to its freedom from various competing processes seen in other rare-earth dopants.Abstract:
The ytterbium-doped fiber amplifier offers a number of attractive features, including a broad-gain bandwidth and a high efficiency, due in large part to its freedom from various competing processes seen in other rare-earth dopants. Here we discuss the main features that influence design and possible applications of ytterbium-doped fiber amplifiers.read more

TL;DR: This analysis shows that if the fiber's MFD could be increased arbitrarily, 36 kW of power could be obtained with diffraction-limited quality from a fiber laser or amplifier, but limits to the scaling of the MFD may restrict fiber lasers to lower output powers.

Strongly pumped fiber lasers
I. Kelson,Amos A. Hardy +1 more
TL;DR: In this paper, the authors analyzed strongly pumped fiber laser systems based on a rate equation model and showed that approximate analytical and quasi-analytical expressions are in excellent agreement with the exact numerical solution of the rate equations, and both agree well with recently published experimental data.
