TL;DR: In this article, a high-brightness laser module is configured with a beamcompression unit capable of reducing a diameter of parallel light beams which are emitted by respective spaced apart individual laser diodes.
Abstract: A high-brightness laser module is configured with a beam-compression unit capable of reducing a diameter of parallel light beams which are emitted by respective spaced apart individual laser diodes. The module further has an objective lens configured to losslessly launch the light with the reduced diameter into a fiber.

TL;DR: In this article, a review of results obtained using three methods which give access to this chemical selectivity: extended X-ray absorption fine structure (EXAFS), anomalous wide-angle Xray scattering (AWAXS) and neutron scattering with isotopic substitutions (NSIS) in glasses is presented.

TL;DR: In this paper, the authors presented a model that links the Q n unit fractions to the melt configurational entropy at the glass transition temperature T g, S conf (T g ), and finally, to its viscosity η.
Abstract: The Adam and Gibbs theory depicts the viscous flow of silicate melts as governed by the cooperative re-arrangement of molecular sub-systems. Considering that such subsystems involve the silicate Q n units ( n = number of bridging oxygens), this study presents a model that links the Q n unit fractions to the melt configurational entropy at the glass transition temperature T g , S conf (T g ) , and finally, to its viscosity η . With 13 adjustable parameters, the model reproduces η and T g of melts in the Na 2 O-K 2 O-SiO 2 system (60 ≤ [SiO 2 ] ≤ 100 mol%) with 1σ standard deviations of 0.18 log unit and 10.6°, respectively. The model helps understanding the links between the melt chemical composition, structure, S conf and η . For instance, small compositional changes in highly polymerized melts generate important changes in their S conf (T g ) because of an excess of entropy generated by mixing Si between Q 4 and Q 3 units. Changing the melt silica concentration affects the Q n unit distribution, this resulting in non-linear changes in the topological contribution to S conf (T g ) . The model also indicates that, at [SiO 2 ] ≥ 60 mol%, the mixed alkali effect has negligible impact on the silicate glass Q n unit distribution, as corroborated by Raman spectroscopy data on mixed Na-K tri- and tetrasilicate glasses. Such model may be critical to link the melt structure to its physical and thermodynamic properties, but its refinement requires further high-quality quantitative structural data on silicate and aluminosilicate melts.
