Abstract:
We report a laser-diode-pumped 2 μm single-frequency Tm:LuAG laser at room temperature. Two fused-silica etalons were used as mode selectors for the single-frequency operation. The maximum single-frequency output power was 616 mW at wavelength of 2021 nm, with a relative power stability of 0.61%. The wavelength tuning range of the single-frequency Tm:LuAG laser was 11 nm from 2018.714 to 2029.876 nm. The M(2) factors were measured to be 1.38 and 1.36 in the x and y directions, respectively.
