Abstract

We report a high-efficiency diode-end-pumped polycrystalline Yb : Y 2 O 3 ceramic laser. Pumped by a 976 nm laser diode bar and with an absorbed pump power of 2.8 W , cw output power of 1.74 W at 1078 nm , and 0.73 W at 1040 nm were obtained. The slope efficiency was measured to be 82.4% for the 1078 nm laser emission and 57.1% for the 1040 nm laser emission.
