Abstract

A near-diffraction-limited, stable, 18  mJ green source with a pulse width of 16 .7   ns was generated at a 1   kHz 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 15   mJ at 532   nm, the M2 factors were 1.3 and 1.7 in the unstable and stable directions, respectively. The energy pulse stability was 0.8%.
