High-power fiber lasers have seen tremendous development in the last decade, with output
powers exceeding multiple kilowatts from a single fiber. Ytterbium has been at the forefront …

This paper reviews current fibre laser technology and new directions that will improve their
performances. Grating technology and the ability to provide high power operation has driven …

Background Infantile spasms constitute a severe form of epileptic encephalopathy. In the
International Collaborative Infantile Spasms Study (ICISS), we showed that combining …

The quantum defect (QD) is an important issue that demands prompt attention in high-power
fiber lasers. A large QD may aggravate the thermal load in the laser, which would impact the …

We describe novel fiber Raman lasers pumped directly by spectrally combined high power
multimode laser diodes at∼ 975 nm and emitting at∼ 1019 nm. With a commercial …

A large variety of high power, high brightness, rare earth doped fiber lasers have been
demonstrated throughout recent years. Several obstacles, such as modal instabilities, heat …

With home-made fiber perform and special fiber drawing & coating technique, a new-type of
(3+ 1) GTWave fiber theoretically designed for bi-directional pump method, was successfully …

We assess different power limits of cladding-pumped fiber lasers. Despite recent advances
in pump sources, these are still primarily limited by available pump power. We find that it …

We report a 100 W continuous-wave cladding-pumped fiber Raman laser operating at 1120
nm. The fiber Raman laser consists of an 85 m long germanium-doped double-clad fiber in a …

We report on a home-made 2 kW (2+ 1) GT-wave fiber, and demonstrated its use in the
creation of a bidirectional pump amplifier. The constructed all-fiber master oscillator power …
