A LD-pumped sigzag slab Nd:YAG oscillator-amplifier system using a photorefractive ring self-pumped phase conjugate mirror is developed. The photorefractive phase conjugator is optimized in the point view of high-energy pulse capacity, fidelity of phase conjugation and stability. The laser system generates the IR laser pulses of 600 mJ and the second harmonic pulses of 250 mJ at the repetition rate of 100 Hz. Both the IR and the second harmonic have 1.1 times diffraction limited beam quality.
