摘要：
We report on the results from a comparative study on the continuous-wave laser performance of Yb:YGG, Yb: LuGG, and Yb:GGG gallium garnets grown by the optical floating zone technique, conducted under identical experimental conditions. 5-7 W of output powers were generated with the three garnet crystals in a compact linear resonator longitudinally pumped by a diode laser emitting at 970-974 nm. The optical-to-optical and slope efficiencies measured for Yb: YGG amounted to 68% and 80%, respectively, which proved to be much higher than the corresponding efficiencies for Yb: LuGG (49% and 60%) or Yb:GGG (52% and 64%).
