Abstract

Double clad aluminosilicate optical fibre doped with neodymium ions was obtained. Aluminosilicate glasses with low silica (25 mol%) content possess very good optical, thermal and mechanical properties. Simultaneously they are characterized by high solubility of rare earth elements. A set of physical measurements including: DTA, DSC, DL analysis, absorption spectroscopy and thermo-physical properties (thermal stability parameters, refractive index, thermal expansion coefficient, microhardness, density and molar volume) were determined. Double-crucible drawing technique was applied to obtain neodymium doped double clad optical fibre with . Luminescence spectra of aluminosilicate glass and fibre doped with Nd^{3 +} ions are presented.
