Abstract
Laser operation at 2.8 mu m in BaY2F8 with erbium concentrations of 7. 5% and 20% is investigated under laser-diode pumping at 967 nm. Output powers as high as 250 mW and slope efficiencies as high as 24% are ob tained. Results are comparable with those of Er3+:LiYF4 under the same pump conditions. Slope efficiencies above 30% are predicted for optim ized erbium concentrations. (C) 1996 Optical Society of America
