Doped Tellureite Glasses: Extending Near-Infrared Emission For Near-2.0-Um Amplifiers

Tm3+-singly-doped and Tm3+-/Ho3+ codoped TeO2-Bi2O3-ZnO-LiO-Nb2O3 (TBZLN)tellurite glasses were successfully prepared by the melt-quneching technique. Emission characteristics and energy transfer mechanisms were studied upon 785-nm laser diode excitation. A significant enhancement of emission intensity at 1.81um with increasing concentration of Tm3+ ions has been observed while increase in the emission intensity at 2.0um with increasing concentration of Ho3+ has been observed up to the equal concentration of Tm3+ (0.5 mol%) in TBZLN glasses.
