“…In a recent paper, we have already determined the refractive indexes (n) of the glasses of these series. At similar x, the CdI 2 -based glasses possess a higher n [16]. In the chosen core and clad compositions, they are 2.074 and 2.039, respectively.…”

“…The syntheses of the glasses were implemented by the melt-quenching method in a vacuum sealed silica set-up. The sulfur was distilled to remove traces of carbon, hydrogen, sulfide oxide, and water [16]. After homogenization of the molten liquid at 1023 K for several hours, the rods were obtained by quenching in water at room temperature and next an annealing at a temperature below the glass transition temperature (Tg), namely Tg-15 K [17].…”

With the ultimate goal of developing rare-earth doped chalcogenide fiber fabrication for sensing, amplification, and laser applications, a core/clad germanium-gallium sulfide fiber doped with Pr3+ has been fabricated. The compositions of the core and the clad were selected to ensure the positive ∆n by adding CdI2 and CsCl, respectively, in the GeS2-Ga2S3 matrix. The choice of these compositions was also justified from experimental parameters, including characteristic temperatures and viscosity. Moreover, the permanent photo writability of the sulfide glass family by a femtosecond laser is investigated from the perspective of Bragg grating photo-inscription. Structural investigations by Raman spectroscopy are presented and the effect of the Pr3+ rare-earth ion on the structure is underlined. Finally, the emission of the step-index fiber, made by the rod-in-tube technique between 3.1 µm and 5.5 µm (by pumping at 1.55 µm), is demonstrated.

In recent years, a growing interest has settled for optical materials and fibers for the mid infrared (mid-IR) region. This interest originates from societal needs for health and environment for instance, and also from demand for defence applications. Indeed, the mid-IR spectral region contains the atmospheric transparent windows (3-5 μm) and (8-12 μm) where thermal imaging (military and civilian) can take place. The elaboration of chalcogenide microstructured optical fibers (MOFs) permits to combine the mid infrared transmission of chalcogenide glasses up to 18 μm to the unique optical properties of MOFs thanks to the high degree of freedom in the design of their geometrical structure. In this context, additive manufacturing of glass materials appears as an attractive technique to achieve more elaborate designs that can hardly be obtain using more common methods such as the stack-and-draw or molding. Taking advantages of the specific physical properties of chalcogenide glasses such as low Tg and extrusion temperature, we have shown that chalcogenide preforms can be rapidly obtained by fused deposition modeling (FDM) using a customized RepRap-style 3D printed fed with chalcogenide glass rods. Such as-prepared preforms can be drawn into chalcogenide optical fibers. Those early-stage results open a new way for the elaboration of chalcogenide MOFs.

“…14,15 Nevertheless, the relatively high phonon energy in those matrix glasses can suppress MIR fluorescence output. Chalcogenide glasses are considered to be suitable MIR fluorescent materials owing to their advantages of low phonon energy, wide transmission range, and high refractive index, 16,17 so they can exhibit low non-radiation transition rate and large emission cross section. 18,19 The Ga 5 Ge 20 Sb 10 S 65 (GGSS) glass is chosen as the matrix doped with Er 3+ and Pr 3+ for enabling efficient fluorescence.…”

There are numerous vital usages for mid-infrared (MIR) lasers in satellite communication, biomedicine, military, remote sensing, and environmental monitoring. In this work, a progression of Er 3+ ions doped, Er 3+ /Pr 3+ ions codoped Ga 5 Ge 20 Sb 10 S 65 glasses were prepared, and their physical performances and structural characteristics were examined. To understand the non-phononassisted energy transfer mechanism, we recorded the up-conversion and infrared fluorescence emission spectra by pumping with a commercial 980 nm LD. Then the 2.7 µm strong fluorescence signal intensity can be obtained when the doped concentration of Pr 3+ is proper. After the doping of Pr 3+ , fluorescence lifetime results revealed that the lifetimes of the Er 3+ : 4 I 13/2 level fell dramatically from 7.33 to 1.90 ms, which experienced a much more significant decrease in lifetimes than the Er 3+ : 4 I 11/2 level. The MIR fluorescence performances were assessed by the determined J-O parameters and relative emission cross sections. Additionally, the generally huge emission cross sections and the small pump energy show that it is possible to obtain population inversion with relatively small pump energy; thus the Er 3+ /Pr 3+ glasses have great potential to be 2.7 µm laser materials. K E Y W O R D S2.7 µm emission, chalcogenide glass, Er 3+ /Pr 3+ co-doped, Ga 5 Ge 20 Sb 10 S 65 glass INTRODUCTIONRecently, mid-infrared (MIR) lasers about 3 µm certainly stand out enough to be noticed owing to their various useful applications, for example, military countermeasures, remote detecting, environment contamination checking, satellite correspondence, and clinical-medical procedure. [1][2][3][4][5] According to previous studies, Er 3+ is a good candidate material for 2.7 µm MIR emission due to its radiative transition of 4 I 11/2 → 4 I 13/2 . Additionally, with a 980 nm business laser, Er 3+ tends to be easily pumped. [6][7][8] However, it is as yet a critical difficulty to get the productive 2.7 µm emission because of the self-terminating issue; thus, the 4 I 13/2 level has a larger lifetime than the 4 I 11/2 level. Through energy transfer (ET), Pr 3+ , Ho 3+ , Yb 3+ , and Tm 3+ have been added as sensitizers to extinguish the Er 3+ : 4 I 13/2 level, which helps solve the issue of self-terminating.Given that the non-phonon-assisted ET process is a more effective way of quenching the electrons of 4 I 13/2 levels compared with the phonon-helped one.
