Townsend, J.E., Barnes, W.L., Jedrzejewski, K.P. and Grubb, S.G. (1991) Yb3+ sensitised Er3+-doped silica optical fibre with ultrahigh transfer efficiency and gain. Electronics Letters, 27, (21), 1958-1959. (doi:10.1049/el:19911214).

Efficient 1.54µm emmission under 1064nm excitation of Er3+:Yb3+ codoped silica fibre is reported. The energy transfer efficiency from Yb3+ to Er3+, ~95% even under high inversion, is comparable to that in multicomponent glass fibres. The small signal gain of ~45dB is measured and power amplifiers with 145mW output power demonstrated.
