ResumoLaser operation at 2.8 microm in BaY(2)F(8) 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 obtained. Results are comparable with those of Er(3+):LiYF(4) under the same pump conditions. Slope efficiencies above 30% are predicted for optimized erbium concentrations.
