摘要：

Excitation power thresholds and avalanche processes have been investigated on two infrared metastable levels of Nd-doped CeCl3. An internal quantum counter effect obtained with a single laser radiation is shown to be responsible for the avalanche and is used in order to estimate the lifetimes of the two infrared levels.
