Room-temperature, continuous-wave laser action at 2.3 μm corresponding to the 3H4−3H5 transition in Tm3+-doped YLF is achieved. Output powers of 200 mW and a slope efficiency of 15% have been obtained for a pump power of 2 W at 0.78 μm. In addition, continuous tunability of this laser from 2.20 to 2.46 μm is obtained.
