Abstract :
A germanate-tellurite glass (GeO2-TeO2-K2O-Nb2O5 -La2O3) with thulium doping has been investigated for application as a laser material at 2 μm region. Under the 808 nm laser diode pumped, intense 1.8 μm emission is obtained. The maximum value of emission cross-section and the radiative lifetime of Tm3+ around 1.8 μm of Tm3+:3F4 reach 9.62×10-21 cm2 and 2.68 ms, respectively, which indicates that germanate-tellurite glass may provide high gain as a good medium for efficient 2 μm laser system.
