    Abstract: A tellurite glass composition doped with a first lanthanide, preferably Tm, and codoped with another lanthanide oxide, e.g. Ho, is provided. The glass includes 4-12 mole % of alkalihalide XY, X being selected from the group of Li, Na, K, Rb, Cs and Fr and Y being selected from the group of F, Cl, Br and I. A preferred glass contains about 10 mole % of the alkalihalide CsCl. The addition of alkalihalide XY results in an enhanced energy transfer from the first to the second lanthanide ion, whereby the lower energy level of the first lanthanide ion is depopulated. The ratio between upper and lower energy level lifetimes for the first lanthanide ion can be reduced to a value below one, enabling efficient amplifier fibers.

    Abstract: Halide-containing gallium lanthanum sulphide glasses can transmit far into the infrared region of the electromagnetic radiation spectrum due to their low maximum phonon energy. Moreover, they present better UV and/or visible transmission and more importantly, some also exhibit improved glass thermal stability, when compared to those of respective non-halide containing pure gallium lanthanum sulphide glasses. These glasses are well suited for serving as hosts for active materials in making optical waveguide devices such as waveguide (either fibre or planar) lasers, optical amplifiers and superfluorescent sources. In particular, when doped with rare-earth ion such as Pr or Dy , they form the core of a waveguide as an efficient optical amplifier operating in the second telecommunication window at a wavelength around 1.3 mu m.

    Abstract translation: 含卤化镓的镧硫化镧玻璃由于其最小声子能量的低可以传播到电磁辐射光谱的红外区域。 此外，它们表现出更好的UV和/或可见透射率，更重要的是，与相应的非卤化物的纯镓镧硫化物玻璃相比，其还具有改进的玻璃热稳定性。 这些眼镜非常适合作为制造诸如波导（光纤或平面）激光器，光放大器和超荧光源的光波导器件的活性材料的主机。 特别地，当掺杂稀土离子如Pr 3+或Dy 3+时，它们形成波导的核心作为在第二电信窗口中工作的有效的光放大器，其波长约为1.3μm。

    Abstract: Chalcohalide glasses resulting from the association of the following chemical elements: antimony, lead, mercury, bromine, iodine and sulphur. The relative proportions of the cations and anions, expressed as an atomic percentage, are as follows: a) the cations as a whole contain 0 to 90 % of antimony, 0 to 100 % of lead, 0 to 70 % of mercury, the sum of the percentages of antimony plus lead amounting to at least 30 % of the cations as a whole, the sum of the percentages of the cations being equal to 100 %; b) the anions as a whole contain 10 to 95 % of sulphur, 0 to 90 % of bromine, 0 to 80 % of iodine, the sum of the percentages of bromine plus iodine lying between 5 and 90 % of the anions as a whole, the sum of the percentages of the anions being equal to 100 %.

    Abstract: A method of producing glasses with useful optical transmission characteristics includes the steps of melting a charge comprising group III and group IV chalcogenides. Addition of group I and group II halides enhances the solubility of rare earth dopants and permits the fabrication of stable lasers and amplifiers incorporating these glasses.
