Abstract
We report a high-average-power, near-diffraction-limited Er:LuAG laser generating 5 W of power at 1.648μm in either cw or repetitively Q -switched operation. When the laser is Q switched at 9 kHz, we measure 0.52 mJ/pulse . The laser is end pumped by a 20-W erbium fiber laser and achieves >30% optical conversion efficiency and >40% incident slope efficiency. This is, to our knowledge, the highest performance (average power and conversion efficiency) obtained from a bulk solid-state erbium laser.
