Microresonator-based lasers in the two-micron range are interesting for extensive applications. Tm3+ ions provide high gain; therefore, they are promising for laser generation in the two-micron range in various matrices. We developed a simple theoretical model to describe Tm-doped glass microlasers generating in the 1.9–2 μm range with in-band pump at 1.55 μm. Using this model, we calculated threshold pump powers, laser generation wavelengths and slope efficiencies for different parameters of Tm-doped tellurite glass microspheres such as diameters, Q-factors, and thulium ion concentration. In addition, we produced a 320-μm tellurite glass microsphere doped with thulium ions with a concentration of 5·1019 cm−3. We attained lasing at 1.9 μm experimentally in the produced sample with a Q-factor of 106 pumped by a C-band narrow line laser.

The ternary tellurite glass structure (TeO2-ZnO-Na2O) was analysed using the Raman spectroscopy in the range of 300-1000 cm-1. The influence of the concentration of alkali ion oxide on the structural change of tellurite glasses was discussed. It is evident that the network of structural units changes significantly with TeO2:Na2O ratio, which then influences the glass thermal properties. Glass density, molar volume, glass transition temperature, crystallization temperature and viscosity have been measured and calculated. These results provide clear evidence and explanation of the glass structural change.
