Tm(3+):YLF laser continuously tunable between 2.20 and 2.46 microm.
Room-temperature, continuous-wave laser action at 2.3 microm corresponding to the (3)H(4)-(3)H(5) transition in Tm(3+)- 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 microm. In addition, continuous tunability of this laser from 2.20 to 2.46 microm is obtained.
