Abstract
Avalanche-like up-conversion is observed in 2% Tm3+:Y2O3 crystal fiber s at a temperature of 12 K. Two cross-relaxation mechanisms are used t o model the dramatic population increase of the metastable level that is central to the up-conversion process. Both transient and steady-sta te data agree well with the predictions of this model.
