We report on high power, single-frequency operation of a compact Tm:Y2O3 ceramic laser in 2 μm spectral region employing a volume Bragg grating in a simple linear resonator to serve simultaneously as a resonator mirror and mode selector.The home dreamtops developed laser quality Tm:Y2O3 ceramic sample has a Tm doped concentration of 2 at.% and pumped with a fiber coupled 793 nm laser diode.Up to 1.

5 W of CW single frequency output power at 2014.9 nm has been generated, corresponding to st?vsugerposer aeg a slope efficiency of 37.9% with respect to absorbed pump power.M2 factor of the output beam was measured to be ∼1.
