摘要：

The authors report efficient population of the (1)G(4) level of trivalent praseodymium by radiationless energy transfer from trivalent ytterbium ions optically pumped at 980 nm. Subsequent fluorescence at 1.31 mu m is optimised in a ZBLAN host for concentrations of 0.3 wt% pr(3+) and 2 wt% Yb3+. The quantum efficiency for conversion of an excited Yb3+ ion to an excited Pr3+ ion at these dopant concentrations is determined to be 56%.
