The pulse characteristics of a laser diode dual-end-pumped electro-optic Q-switched Nd∶LuAG ceramic laser at various repetition rates are presented.The largest output pulse energy of 11 mJ is realized at the repetition rate of 100 Hz with pump energy of 84.3 m J,and the slope efficiency in respect to pump pulse energy is 18.6％.The single pulse peak power reaches up to 1.57 MW.Using Nd∶LuAG ceramic as the amplification medium seeded by an Nd∶YAG laser of 5.2 m J,a 10.3 mJ amplified pulse is obtained with pump pulse energy of 42.8 mJ,corresponding to an extraction efficiency of 11.9％.
