摘要：

We report on high power, single-frequency operation of a compact Tm:Y2O3 ceramic laser in 2 mu m spectral region employing a volume Bragg grating in a simple linear resonator to serve simultaneously as a resonator mirror and mode selector. The home 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 a slope efficiency of 37.9% with respect to absorbed pump power. M-2 factor of the output beam was measured to be similar to 1.03.
