The manufacturing and properties of double-clad optical fibres

摘要

In this paper we present synthesis, physical and optical properties of silica based glass doped with 1,5% wt. neodymium ions. The stable silica glass without crystallization effect was synthesized. Fabricated glass was applied as core to obtain double clad optical fibers. Rod-in-tube method drawing technique was used to fabricate double clad optical active fibers with D- profile inner cladding. Absorption and luminescence spectra of obtained fibers were measured.
