摘要：

We describe a diode-pumped master-oscillator power-amplifier system with two-rod Nd:YAG media and double-stage relay optics scheme. At the repetition rate of 2.4 kHz it delivers an average power of 108 W with Q-switched pulses of 47 ns duration. The laser beam is characterized by an M-2 factor of 2.5 x 2.7. A model of amplification, which takes into account the temporal overlap between the beams that propagate forwards and backwards in the amplifier stage, was developed to explain the experimental results.
