Paper Abstract

A high-gain, high-energy extraction efficiency, phase-conjugated, multiple-pass amplifier was developed using Nd:YAG. The amplifier was used with a low-energy, self-injection locked, passively Q-switched, highrepetition-rate oscillator to obtain energies of 0.85 J in SLM laser pulses of durations variable between <7 and >17 ns. At high repetition rates (20 Hz), the average power reached 14.5 W. Beam quality was better than 2 x diffraction limited. A two-dimensional multiple-pass model was developed for the purpose of interpretation and design.
