The optical properties of rare earth doped chalcogenide glasses have received a considerable amount of interest in recent years, primarily because of their very low multiphonon decay rates when compared with other glass hosts. In this paper we compar

In light of the recent progress on the fabrication of GaLaS fibres we have modelled the performance of dysprosium doped GaLaS fibre amplifiers operating at 1.3µm. Based on experimental data, we find the incorporation of a co-dopant (terbium) in the

The performance of Er3+:Yb3+ single frequency fiber lasers is reported. With lasing powers up to 60mW, they are shown to have excellent specifications in terms of optical linewidth, signal-to-noise ratio, RIN, SMSR and polarisation purity.

We report on laser action in a Neodymium doped Gallium Lanthanum Sulphide glass fibre. Laser action at 1080nm was obtained in a 22mm long multimode glass fibre with a neodymium doped core, fabricated by the rod-in-tube technique. The laser was pumped

Diode-pumped rare-earth doped fibre lasers in the mid-infrared wavelengths region would offer a compact and efficient alternative to the either relatively weak or very complex existing mid-infrared sources such as thermal emitters, gas lasers and OPO

We report laser action in a neodymium doped gallium lanthanum sulphide glass fibre at 1.08µm. To our knowledge, this is the first demonstration of laser action in a rare-earth doped chalcogenide glass fibre.

The characteristics of a high power Er3+:Yb3+ single frequency fiber laser pumped at 980nm are reported. The device gives 60mW output power with RIN 10MHz and linewidth 500kHz. At low output powers (< 30mW) the slope efficiency is as high as 25%, fal

Gallium lanthanum sulphide (Ga:La:S) glass is now emerging as a promising material for active optical fibre device applications and in particular new fibre amplifiers and lasers. Recent success in fibre drawing, long wavelength spectroscopy and the d

An intracavity pumping scheme for achieving higher output powers from 1.55µm DFB fiber lasers is proposed and demonstrated. By placing the DFB laser inside the cavity of a Yb3+-fiber laser, up to 3 times higher power has been obtained when compared
