The methods of glass preparation and their properties are showed. A set of physical measurements including: DTA, DSC, DL analysis, absorption spectroscopy, visible and infrared absorption edges and thermo-physical properties were determined. The stable glass compositions were doped with rare earth elements. Selected properties of obtained glasses are: high transmission, refractive index 1.53-1.68, high solubility of RE ions (up to 10 wt%). Double-crucible and rod-in-tube drawing techniques were applied to obtain aluminosilicate and phosphate double clad optical fibres doped with neodymium and ytterbium ions. Luminescence spectra of manufactured glasses and fibres are presented.}, type={Artykuły / Articles}, title={Rare earth ions doped aluminosilicate and phosphate double clad optical fibres}, URL={http://ochroma.man.poznan.pl/Content/110738/PDF-MASTER/(56-2)103.pdf}, keywords={rare-earths in glasses, double clad optical fibre, oxide glasses, low silica glass}, }
