CW and quasi-CW laser performance of 10 at.% Yb3+:LuAG ceramic

We have investigated the laser oscillation of 10 at.% Yb3+:LuAG ceramic pumping into the two main absorption peaks in CW and quasi-CW operation modes. Emitting at 1030 and 1046 nm the laser achieves excellent performance, delivering output powers up to 8.8 W. The highest estimated slope efficiencies are 72.6% in CW and 79% in quasi-CW. A tunability range of 57.5 nm is measured.
