Abstract
We developed a Nd:YAG rod-based MOPA to generate high power in a radially polarized beam. Two pump-chambers in the amplifier section produced 2.1kW @ M2=9.5, while three pump-chambers yielded 3.1kW @ M2=14. Efficiency in the last pump-chamber was 33%. Several techniques were utilized to enhance beam-quality: a radially polarized oscillator, special pump-chambers, external compensation of lower-order aberrations, and high-order aberration compensation by pairing pump-chambers.
