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 …

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 …

We report a novel type of active fiber–tapered double clad fiber suitable for pum** by low
brightness sources with large beam parameter product of 50÷ 300 mm× mrad. Ytterbium …

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 …

Recent developments of compact white-light supercontinuum laser sources are reviewed.
Basically these sources make use of a sub-nanosecond microchip laser and a photonic …

We detail the design and performance of a high efficiency in-band pumped thulium fiber
amplifier operating at the 100 W level. Using a novel pum** architecture based on three …

Lasers have progressed a long way from a point where they were famously regarded as a
solution looking for a problem to the present day wherein there is nearly no field that has …

We report the analysis of multimode pump absorption in double-clad rare-earth-doped fibers
under realistic bending conditions. The finite-element beam-propagation method is used for …

We generate 9.3-W continuous-wave 1535-nm multimode output from a 7.0-cm short-length
Er-Yb codoped phosphate fiber laser. A slope efficiency of 29% is obtained at pump powers …

A theoretical analysis of strongly pumped Yb-doped double-clad fiber lasers is presented
and an approximate analytic function of distributed laser along the whole fiber with the …
