New class of fibre laser based on lead-germanate glass
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 Tm<sup>3+</sup> <sup>3</sup>H<sub>4</sub> - <sup>3&l...
