摘要：

An analysis of the photoluminescence properties of Cr:Er:GGG indicates that the erbium emission at 1.6-mu-m and 2.8-mu-m can be efficiently sensitized by a chromium co-doping. Increasing the erbium concentration enhances the 2.8-mu-m emission, while the 1.6-mu-m emission decreases. This effect is due to a cooperative upconversion of two erbium ions in the 4I13/2 state. The lifetime of the 2.8-mu-m emission in Cr:Er:GGG is 1.3 ms which is about an order of magnitude longer than in Er:YAG.
