“…One of the main impediments to the development of efficient lanthanide ion doped low phonon energy glass fibre lasers for the MIR wavelength range is that, so far, an efficient 3 or 4 level system for this wavelength range has not been identified. Prudenzano et al (2009) have suggested development of Er 3+ doped photonic crystal fibre lasers and demonstrated their feasibility with conversion efficiency of up to 15% at a fibre loss of 2 dB/m. However, to date, no successful realisation of a lanthanide ion doped photonic crystal fibre of chalcogenide glass has been reported.…”

A simple Dy 3+ -doped chalcogenide glass fibre laser design for mid-infrared light generation is studied using a one dimensional rate equation model. The fibre laser design employs the concept of cascade lasing. The results obtained demonstrate that efficient cascade lasing may be achieved in practice without the need for fibre grating fabrication, as a sufficient level of feedback for laser action is provided by Fresnel light reflection at chalcogenide glass fibre-air interfaces. Further enhancement of the laser efficiency can be achieved by terminating one of the fibre ends with a mirror. A numerical analysis of the effect of the Dy 3+ doping concentration and fibre loss on the laser operation shows that with 5 W of pump power, at 1.71 µm wavelength, output powers above 100 mW at ∼ 4.5 µm wavelength can be achieved with Dy 3+ ion concentrations as low as 3 × 10 19 cm −3 , when fibre loss is of the order 1dB/m.

“…Mid-IR fluorescence can be obtained by doping and/or codoping a chalcogenide glass with luminescent rare-earth (RE) ions, such as Er 3+ , Pr 3+ , Nd 3+ ,Tb 3+ , Dy 3+ and Ho 3+ [185][186][187][188][189]. The low phonon energy exhibited by the chalcogenide glass matrix permits mid-IR transmission beyond 10 µm.…”

Applications involving optical fibers have grown considerably in recent years with intense levels of research having been focused on the development of not only new generations of optical fiber materials and designs, but also on new processes for their preparation. In this paper, we review the latest developments in advanced materials for optical fibers ranging from silica, to semi-conductors, to particle-containing glasses, to chalcogenides and also in process-related innovations.

“…In conclusion, both the theoretical and experimental results demonstrated the suitability of the 2S2G chalcogenide glass as a very attractive candidate to construct fiber laser sources and amplifiers operating in the mid-IR spectral region. Moreover, the feasibility of a novel Er 3+ -doped 2S2G chalcogenide fiber laser, pumped at the wavelength 806 nm, designed in order to obtain high performance at the wavelength 4.5 μm, is investigated in [37]. In particular, the developed numerical code takes into account the erbium energy levels lifetimes, the emission and absorption cross section measured on 10000 ppm Er 3+ -doped 2S2G preliminary sample.…”

Rare-earth-doped chalcogenide glass fiber lasers and amplifiers have great applicative potential in many fields since they are key elements in the near and medium-infrared (mid-IR) wavelength range. In this paper, a review, even if not exhaustive, on amplification and lasing obtained by employing rare-earth-doped chalcogenide photonic crystal fibers is reported. Materials, devices, and feasible applications in the mid-IR are briefly mentioned.
