We present a high-power Ho∶YAG ceramic laser pumped at 1908nm.Using a dual-end-pumped structure,the maximum continuous-wave output power of 48 W is obtained,corresponding to a slope efficiency of 70.4％ with respect to the absorbed pump power.At actively Q-switched mode,the maximum average output power of 46 W and the minimum pulse width of 21 ns are achieved at a pulse repetition frequency of 20 kHz,corresponding to a peak power of approximately 109.5kW.In addition,the beam-quality M2 factor is found to be 1.4 at the maximum output power.
