摘要：

We report the sudden appearance of upconversion fluorescence and resonant increasing absorption above a threshold intensity in Tm.YALO3 at room temperature. These effects are shown to arise from nonlinear, cooperative, excited-state dynamics. Comparison with quantum theory reveals essential roles both for pairwise cross relaxation and excitation migration among Tm impurity ions.
