Paper 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: an azimuthally-polarized
oscillator, special pump-chambers, external compensation of lower-order aberrations, and high-order aberration
compensation by pairing pump-chambers.
