摘要: By conventional melting and quenching methods, 3Yb2O3-0.2Tm2O3-xHo2O3 (wt%, x=0.2∼1.2) was doped into an easily fiberized tellurite glass with composition of 78TeO2-10ZnO-12Na2O (mol%) to form YTH-TZN78 glasses. Under 976 nm excitation, the direct sensitizing effect Yb ions (Yb→Ho) indirect self-depopulating effects Tm (Yb→Tm→Ho) were found present intense red upconversion emission at 657 nm (Red, Ho: F55→I58) responsible for absence usually observed 484 nm (Blue, Tm:G14→H36). Regardless dopant concentration Ho ions, intensity Ho: F55→I85) is about three times stronger than that green one 543 nm (Green, Ho: S52→I85). For this certain 657 nm, 0.4 wt% Ho2O3-doped highest therefore determined as a promising active fiber laser development.
