A near-diffraction-limited, stable, green source with a pulse width of was generated at a repetition rate by frequency doubling of diode stacks end-pumped electro-optically Q-switched slab Nd:YAG oscillator-amplifier system. The pump to green optical conversion efficiency was 10.7%. At the output energy of at , the factors were 1.3 and 1.7 in the unstable and stable directions, respectively. The energy pulse stability was .
