title: Continuous-wave and Q-switched operation of a resonantly pumped polycrystalline ceramic Ho:LuAG laser.
abstract: We have reported continuous-wave (CW) and Q-switched operations of a polycrystalline ceramic Ho:LuAG laser in band pumped by a Tm:fiber laser at the wavelength of 1907 nm. By using an output coupler of 20% transmission, maximum continuous-wave output power of 2.87 W for 9.72 W of incident pump power was achieved, corresponding to a slope efficiency of 31.9%. Shortest pulse duration of 21.0 ns with peak power of 28.2 kW has been obtained at 500 Hz pulse repetition frequency (PRF) under 5.65 W of incident pump power.
