High Power Single Frequency Tm:Y<sub>2</sub>O<sub>3</sub> Ceramic Laser at 2015 nm
Abstrak
We report on high power, single-frequency operation of a compact Tm:Y<sub>2</sub>O<sub>3</sub> 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 developed laser quality Tm:Y<sub>2</sub>O<sub>3</sub> 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<sup>2</sup> factor of the output beam was measured to be ∼1.03.
