“…Chalcogenide fibers are generally investigated for nonlinear wavelength transfer due to their high nonlinearity [8,9]. Though there are some studies on rare-earth-doped chalcogenide fiber lasers and amplifiers [10][11][12][13], their efficiencies and output powers are relatively low due to the low available rare-earth doping level (∼0.1 mol%), the large background loss (0.5-1 dB/m), and the fragility of chalcogenide glasses. Significant longterm efforts are needed before the realization of high output power chalcogenide fiber lasers for practical applications.…”

-NaF), considered as the most stable heavy metal fluoride glass and the excellent host for rare-earth ions, has been extensively used for efficient and compact ultraviolet, visible, and infrared fiber lasers due to its low intrinsic loss, wide transparency window, and small phonon energy. In this paper, the historical progress and the properties of fluoride glasses and the fabrication of ZBLAN fibers are briefly described. Advances of infrared, upconversion, and supercontinuum ZBLAN fiber lasers are addressed in detail. Finally, constraints on the power scaling of ZBLAN fiber lasers are analyzed and discussed. ZBLAN fiber lasers are showing promise of generating high-power emissions covering from ultraviolet to mid-infrared considering the recent advances in newly designed optical fibers, beam-shaped high-power pump diodes, beam combining techniques, and heatdissipating technology.

“…These properties allow fluorescence with higher efficiencies and at longer wavelengths than in other rare earth doped glass [12] and could result in a new generation of solid state mid infrared lasers. There has been considerable work on chalcogenide glasses based on gallium lanthanum sulphide (GLS) as a laser and amplifying medium [12][13][14][15]. Compared to other chalcogenides GLS lends itself to active applications because of its excellent rare earth solubility [16].…”

“…As can be seen, the emission cross sections are larger and the radiative lifetimes shorter than those reported for other glass hosts making this material a good candidate for laser applications [16]. The first reported chalcogenide lasers by Scheiwzer [14] and later Mairaj [15] exploited optical fibre and optical waveguide cavities formed in GLS glass. With the achievement of GLS microspheres by Elliott in 2007 [18] we set out to demonstrate laser action from an Nd 3+ doped GLS sphere.…”

Abstract:Laser action has been demonstrated in chalcogenide glass microsphere. A sub millimeter neodymium-doped gallium lanthanum sulphide glass sphere was pumped at 808 nm with a laser diode and single and multimode laser action demonstrated at wavelengths between 1075 and 1086 nm. The gallium lanthanum sulphide family of glass offer higher thermal stability compared to other chalcogenide glasses, and this, along with an optimized Q-factor for the microcavity allowed laser action to be achieved. When varying the pump power, changes in the output spectrum suggest nonlinear and/or thermal effects have a strong effect on laser action.

“…In particular the sulfides glasses deserve special attention because they can be fibered and laser action has been demonstrated in neodymium ͑Nd 3+ ͒ doped gallium-lanthanum-sulphide glass bulk 5 and fiber. 6 Another glass composition of interest is Ga 10 Ge 25 S 65 ͑GGS͒ that has wide transparency window from the infrared to the blue/green region and low phonon energy ͑Ϸ370 cm −1 ͒. Recently the optical properties of GGS glass doped with Nd 3+ , 7 Pr 3+ , 8 and Er 3+ ions 9 were investigated.…”

We report on photoluminescence ͑PL͒ properties of Er 3+ doped Ga 10 Ge 25 S 65 glass. Experiments were performed using 5 ns laser pulses at 980 nm ͑532 nm͒, in resonance with the 4 I 15/2 → 4 I 11/2 ͑ 4 I 15/2 → 2 H 11/2 ͒ transition of the Er 3+ ions. PL bands were observed from the blue to the near-infrared and the dependence of their intensity as a function of the laser intensity was analyzed. The PL temporal behavior was analyzed through rate equations for the population densities and using the Inokuti-Hirayama model. The results allowed identification of the PL pathways and the characterization of energy transfer processes involving pairs of ions.
