Fibre lasers operating at the mid-IR have attracted enormous interest due to the plethora of
applications in defence, security, medicine, and so on. However, no continuous-wave (CW) …

We present the characteristics of a continuous-wave (CW) mid-infrared fiber laser source
based on HBr-filled hollow-core fibers (HCFs) made of silica. The laser source delivers a …

Rare-earth-doped fiber lasers at 3–5 μm can provide a variety of applications in defense,
security, medicine, and so on. Limited by the maximum phonon energy of silicate glass host …

We report here the characteristics of a nanosecond high-power mid-infrared (mid-IR) light
source based on an anti-resonant hollow-core fiber (AR-HCF) filled with acetylene gas. It is …

We report the highest power operation of a resonantly cladding-pumped, holmium-doped
silica fibre laser. The cladding pumped all-glass fibre utilises a fluorine doped glass layer to …

High-power and widely tunable Tm-doped silica fibre lasers cladding-pumped and core-
pumped by a 1565 nm Er, Yb fibre laser are reported. Output power up to 19.2 W was …

The emission band of holmium-doped silica fibers extends beyond 2200 nm, which means
these lasers have the potential of covering considerable parts of the atmospheric …

We present the pedestal-free thulium doped silica fiber with a large nanostructured core
optimized for fiber lasers. The fiber is composed of over 6 thousand thulium doped silica …

An all-fiber, narrow-linewidth, high power Yb-doped silica fiber laser at 1179 nm has been
demonstrated. More than 12 W output power has been obtained, corresponding to a slope …

We report here the characteristics of a continuous wave (CW) high-power mid-infrared (mid-
IR) light source based on acetylene-filled anti-resonant hollow-core fiber (HCF). It is a single …
