“…The authors operated with a lithium tellurite glass doped with Nd 3+ and showed that a continuous wave (cw) laser action can be obtained for a longitudinally argon pumped (514.5 nm) compact structure. Then, Balashov et al conducted laser studies on a tellurite bulk glass doped with Nd 3+ [15], where they managed to reach approximately 10% efficiency. For these two papers [14,15], nothing was mentioned regarding the geometry/dimensions of the laser cavity.…”

“…The easiest way to review all these references remains to classify them into three categories, based on the nature of the rare earth ions incorporated: -The first category corresponds to papers dealing with Nd 3+ -doped tellurite glass bulk lasers [14][15][16][17][18][19][20][21], where the laser emission line is $1065 nm (only one exception relates about some laser emission at 1.37 lm).…”

“…Papers related to tellurite bulk lasers [14][15][16][17][18][19][20][21][22][23][24][25][26][27] can be sorted in different categories, depending on the nature of the rare earth ions incorporated into the tellurite matrix in order to access a variety of laser emission lines or depending on the type of laser cavity (cavity with sample placed normally to the laser beam, cavity with sample placed at the Brewster angle), etc. The easiest way to review all these references remains to classify them into three categories, based on the nature of the rare earth ions incorporated: -The first category corresponds to papers dealing with Nd 3+ -doped tellurite glass bulk lasers [14][15][16][17][18][19][20][21], where the laser emission line is $1065 nm (only one exception relates about some laser emission at 1.37 lm).…”

“…Tellurite lasers can be found under diverse forms: as fiber lasers [11][12], as microcavity lasers such as microspheres, microdisks and rings, which are well documented by He et al [13], or finally as bulk lasers [14][15][16][17][18][19][20][21][22][23][24][25][26][27]. As we are only interested in the last type of lasers, we are going to review the literature treating specifically about tellurite bulk lasers.…”

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...
