Abstract
Spectroscopic properties of erbium (Er3+)-, holmium (Ho3+)-, dysprosium (Dy3+)doped and Er3+/Ho3+, Er3+/Dy3+ co-doped ZBLAN (ZrF4-BaF2-LaF3-AlF3-NaF) glasses were studied. The experimental results show that efficient energy transfer from Er3+ to Ho3+ and Dy3+ occurs in the Er3+/Ho3+ and Er3+/Dy3+ co-doped ZBLAN glasses, respectively. This valuable discovery enables us to design and develop high power Ho3+-doped and Dy3+-doped ZBLAN fiber lasers in the 3 µm wavelength region that can be pumped with readily available high-efficiency, high-power diode laser pumps at 980 nm.
