Abstract ：We demonstrate a cw and actively Q-switched Er:LuAG laser resonantly dual-end-pumped by 1532 nm fibre-coupled laser diodes. A maximum cw output power of 1.9 W at 1650.3 nm is obtained at a pump power of 25.5 W, corresponding to a slope efficiency of 43.3%. In the Q-switched regime, the maximum pulse energy of 3.51 mJ is reached at a pulse repetition rate of 100 Hz, a pulse duration of 90.5 ns and a pump power of 25.5 W. At the repetition rate of 400 Hz, the output energy is 2.12 mJ, corresponding to a pulse duration of 125.4 ns.
