We report a LD side-pumped high beam quality (M (x) (2) = 1.20 and M (y) (2) = 1.19) acousto-optic (AO) Q-switched single-rod Nd:YAG laser with a TEM(00)-mode dynamic stable cavity. At the pump power of 600 W, 41 W TEM(00)-mode 1064 nm laser was achieved with electro-optical conversion efficiency of 7%. The repetition rate and pulse width were 30 kHz and 102 ns, respectively with pulse energy of 1.4 mJ and peak power of 13 kW. Up to 24 W of 532 nm green laser was generated by external frequency doubling, corresponding to 59% optical conversion efficiency.
