Paper Abstract

Following the initial discovery of fluorozirconate glasses in 1974 it was immediately recognised that this glass system had a number of important differences to the more conventional oxide glasses. Firstly their extended IR transmission gave them potential as IR optical fibres with intrinsic losses well below those available in silica. Indeed a considerable amount of work has already been directed at this application [1]. A second important property that was soon recognised their potential as laser host glasses and early measurements of fluorescence spectra from rare earth ions confirmed their usefulness in this area. More recently it has been recognised that "active fibres" made by doping with rare earth ions may play an important role in telecommunications, both as sources and in-line fibre amplifiers [2]. A logical step therefore would be to investigate active fluoride fibres doped with rare earths and the work presented in this paper describes recent work in this area. The dopants studied are Nd, Ho and Er which have been made to lase at different wavelengths over the range 1.0 to 3.0 um.
