Low differential phase noise ytterbium-doped fiber amplifier system for coherent beam combination
Optoelectronic Research Centre, University of Southampton, Southampton SO17 1BJ, United Kingdom
Published online: 18 October 2024
A two-channel ytterbium-doped fiber amplifier system with active phase-locking reaches a differential phase noise of only 40 mrad (X/160) at 200-W channel power. Frequencies above 30 Hz did not require noise suppression, thus simplifying advanced beam-shaping through coherent beam combination.
