We have relized a laser diode-end pumped acousto-optic Q-switched laser with a Nd:CTGS crystal. Stable actively Q-switched laser was obtained at wavelength of 1065 nm. Under an absorbed pump power of 14.5W, an actively Q-switched laser with average output power of 894 mW was obtained at the repetition rate of 15 kHz. When the repetition rate was 5 kHz, an actively Q-switched laser with the minimum pulse width of 38 ns, the peak output power of 3.07 kW, and the pulse energy of 110.6 μJ was demonstrated..
