We report on the laser emission of the polycrystalline ceramic obtained from the full and congruent crystallization of the parent glass 1Nd 3+ :75TeO 2 -12.5Bi 2 O 3 -12.5Nb 2 O 5 composition. In particular, the current work underlines the importance of carefully controlling the heat treatment in order to solely crystallize the Bi 0.8 Nb 0.8 Te 2.4 O 8 cubic phase and consequently avoid the formation of the BiNbTe 2 O 8 orthorhombic phase that would be detrimental for optical purpose. The structure, microstructure and photoluminescence properties of the resulting transparent tellurite ceramics are characterized. The continuous-wave and gain-switching laser performances reveal that the emission remains perfectly single transversal mode in the range of pump powers explored. The maximum output power achieved was ~28.5 mW, for a pump power threshold of ~67 mW, and with associated efficiency and slope efficiency of ~22.5% and ~50%, respectively. These data definitely stand among the best results obtained so far for bulk laser tellurite materials and thus demonstrate the potential of such polycrystalline transparent ceramics as optically active materials. Finally, the laser emission characteristics in pulsed regime, at low and high repetition rates, are also provided: more than 6.5 W of peak power at a repetition rate of 728 kHz can be obtained.Tellurite based-glasses present numerous advantages, such as a large transparency window up to ~6 µm, a rather low melting point and excellent third-order non-linear optical properties . These are key parameters which will favour radiative transitions, further permitting laser emission.So far, all the literature dedicated to tellurite bulk lasers is still rather scarce, as it was recently reviewed in 5, and most of all, is limited to bulk glass lasers [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21] . The most convenient way to sort all these contributions remains to classify them into three categories, which find their origin from the nature of the rare earth ions employed. Hence, papers dealing with Nd 3+ -doped tellurite glass bulk lasers are the most abundant 6-15 : except one of them which treats the lasing properties at 1.37 μm, they are all related to laser emission around 1064 nm. Then, one can find articles reporting on Ho 3+ -doped, Tm 3+ -doped and also Tm 3+ -Ho 3+ co-doped tellurite glasses for laser emission around 2 μm [16][17][18][19] . Finally, the last category regroups papers focused on Yb 3+ -doped tellurite glasses, emitting in the 0.9-1.1 μm range, like in 20 .Besides that, there is some important and recent research activity concentrated on the study of the optical properties of tellurite glass-ceramics, considered as promising materials for lasers, especially in the near and mid-infrared [21][22][23] . However, to the authors knowledge, laser emission in bulk tellurite glass-ceramics has not yet been reported.On another hand, a very interesting and innovative way of producing some transparent ceramics is the full congruent crystallization met...

“…TeO 2 based-materials present numerous advantages over silicates, especially regarding enlargement of transparency in the infrared region up to 6 μm, lower melting point, higher linear refractive index, better solubility of rare-earth ions for optical emission properties, and excellent nonlinear optical properties [1,2]. Tellurite glasses have been reported to develop optical devices such as white LEDs [3], or with specific emission around 2.7 μm [4], or lasing properties [5,6] and glass fibers for supercontinuum generation [7,8].…”

New transparent defect pyrochlore KNbTeO 6 ceramics were successfully prepared by Spark Plasma Sintering (SPS) of same composition polycrystalline powders elaborated by classic solid-state reaction from oxide precursors (K 2 CO 3 , Nb 2 O 5 , TeO 2 ) and followed by high energy milling powders. As such precursors are not available as commercial nanopowders, a suitable process has been developed by combining solid-state reactions and high energy milling. The determination of appropriate consolidation conditions and sintering parameters of the green body such prepared, are described in this paper. The resulting ceramic is transparent in both the visible and near infrared range (up to 5.5 μm). The maximum of transmittance is reached in the near infrared region around 2500 nm with a value of 78 % (1 mm thick sample), close to the maximum theoretical value of transmittance. This transparent KNbTeO 6 ceramic demonstrates a homogeneous and dense microstructure with an average grain size less than 500 nm. A small content of secondary phase has been detected by nanoscale observations without drastic effects on transparency. This ceramic exhibits very good mechanical properties similar to the Y 2 O 3 transparent ceramic, as well as interesting dielectric properties in the microwave range. This innovative method should drive the development of new transparent materials with technologically relevant applications.

“…To the best of our knowledge, aside from few investigations on the specific compositions given below, there is no reported systematic study within this ternary glass system. Carreaud et al [44] and Dai et al [45] recorded the Raman spectra of 75TeO 2 -20NbO 2.5 -5WO 3 and 72TeO 2 -18NbO 2.5 -10WO 3 glass compositions respectively along with their thermal and linear optical properties; Muñoz-Martín [46] measured the linear and nonlinear optical properties of the 80TeO 2 -5Nb 2 O 5 -15WO 3 glass composition. In addition, Er 3+ and Yb 3+ doped TeO 2 -Nb 2 O 5 -WO 3 glass compositions have been investigated as potential candidate materials for broadband amplifiers [47,48].…”

The glass-forming domain, density, thermal, structural and optical properties of new glasses within the TeO2-NbO2.5-WO3 system have been investigated. By means of Raman spectroscopy, a thorough structural analysis of these glasses has been undertaken on the basis of a full-scale spectral decomposition process. The optical transmission window, refractive index dispersion and third-order nonlinear susceptibilities χ (3) were measured by UV-Vis-NIR spectroscopy, spectroscopic ellipsometry and Z-scan method respectively. Consistent correlations are successfully established between the measured structural, linear and nonlinear optical properties. In general, the structural features of the glass network are found to evolve mildly upon adding NbO2.5 or WO3. Nonetheless, a weak structural depolymerization of the Te-O-Te bond network as a result of adding NbO2.5 is evidenced and discussed in detail.
