We report an 885 nm laser diode (LD) end pumped high beam quality ( = 1.322, = 1.235) electro optical Q switched Nd:YAG laser with TEM 00 mode output for the first time. At the absorbed pump power of 59.5 W, a 22.7 W 1064 nm laser was achieved at 10 kHz repetition rate with optical to optical effi ciency of 38.1%. The maximum pulse energy and shortest pulse width were 5.1 mJ and 14.5 ns at 2 kHz rep etition rate, and the calculated peak power was 352 kW.
