Abstract
We report a compact Ho:LuAG ceramic laser intracavity pumped by a diode-pumped Tm:YAG ceramic laser. The laser oscillation is accomplished by using a common linear cavity configuration containing Tm:YAG and Ho:LuAG ceramics. The 1.0 at.% Ho:LuAG ceramic laser yields 1.15 W of maximum output simultaneously at 2094 and 2100 nm with a beam quality factor of M.2.~.2.8.
