Abstract

Rare-earth doped single-mode optical fibres have led to the development of a range of active fibre devices with numerous applications in telecommunications non-linear optics, spectroscopy and fibre sensors. These devices possess a number of advantages over their bulk counterparts. By virtue of their small active areas, very-low thresholds and high gains can be achieved and this has allowed the demonstration of lasing action on transitions never previously observed in glass. Since the typical fibre diameter is 125µm, thermal effects which plague bulk-glass lasers are minimal. Silica, the host material, has good power-handling characteristics; moreover, it broadens the rare-earth transitions, enabling highly tunable lasers at various wavelengths to be constructed. In this paper, the techniques for tuning fibre lasers are first discussed and the results obtained for different dopants and host glasses presented. Finally, the results obtained are critically compared and some suggestions for future directions are discussed.
