摘要：

Efficient cw operation of the Er3+:GSGG I-4(11/2) --> I-4(13/2) laser transition at 2.8-mu-m is demonstrated at room temperature. The I-4(11/2) upper laser state is directly pumped at 0.97-mu-m. The slope efficiency for the 2.8-mu-m laser is 36%, indicating a greater than unity quantum efficiency. This excess efficiency results from the recycling of population through upconversion out of the lower laser state.
