Abstract
We report a high-average-power, near-diffraction-limited Er:LuAG laser generating 5 W of power at in either cw or repetitively -switched operation. When the laser is switched at 9 kHz, we measure . The laser is end pumped by a 20-W erbium fiber laser and achieves optical conversion efficiency and incident slope efficiency. This is, to our knowledge, the highest performance (average power and conversion efficiency) obtained from a bulk solid-state erbium laser.
