摘要：
We report a high-efficiency diode-end-pumped polycrystalline Yb:Y2O3 ceramic laser. Pumped by a 976 nm laser diode bar and with an absorbed pump power of 2.8 W, ew output power of 1.74 W at 1078 nm, and 0.73W at 1040nm were obtained. The slope efficiency was measured to be 82.4% for the 1078nm laser emission and 57.1% for the 1040 nm laser emission. (c) 2007 Optical Society of America.
