Paper Abstract

Neodymium and Erbium doped Silica-based optical fibres are a promising material in fibre laser and amplifier. The match-type with Si02 cladding and Ge0z-Si02 core single-mode fibres were fabricated by NCVD soot method. Rare-earth were doped by a soot imprenation technique. The fibres with various amounts of Nd3+·and Er3+codoping with Yb3+were also obtained. The quantity of dopants can be controlled by deposition temperature and doping concentrations in solution. The absorption spectrum and fluorescence characteristics were measured. The concentration of rare-earth ion in fibre can be in excess of 1 wt%. The minimum attenuation can be as low as 5-10 db/km at lasing wavelength. 1.555 um optical laser and amplifier had been made by Er3+/Yb3+doped optical fibre. The output of laser is >6 mw.
