Efficient cw operation of the Er3+:GSGG 4I11/2 → 4I13/2 laser transition at 2.8 μm is demonstrated at room temperature. The 4I11/2 upper laser state is directly pumped at 0.97 μm. The slope efficiency for the 2.8-μm 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.
