Lincoln, J.R., Mackechnie, C.J., Wang, J., Brocklesby, W.S., Deol, R.S., Pearson, A., Hanna, D.C. and Payne, D.N. (1992) New class of fibre laser based on lead-germanate glass Electronics Letters, 28, (11), pp. 1021-1022. (doi:10.1049/el:19920648).

Record type: Article


The first fibre laser based on rare-earth doped lead-germanate glass is reported. The thulium-doped fibre had a background loss of 2 dB/m and a maximum phonon energy of ~920 /cm. Lasing was achieved on the Tm3+ 3H4 - 3H6 transition at 1.905µm with a 3.6mW threshold, when diode-pumped at 790nm. A quantum efficiency of 30% was obtained.
