摘要：
We report on a high-power diode-end-pumped polycrystalline Yb:Y2O3 ceramic laser. Under the pump power of 27 W, continuous-wave output power of 9.2 W at 1078 nm has been obtained by using an output coupler of R=96%. The laser had a threshold of 3.1 W and a slope efficiency of 41%. Comparative studies on the laser performance between the Yb:Y2O3 ceramic and the Yb:yttrium aluminum garnet (YAG) single crystal show that at the same doping concentration of 8 at. %, higher laser efficiency can be obtained in the Yb:Y2O3 ceramic laser than in the Yb:YAG single crystal laser.
