Abstract

In this paper we combine the master-oscillator power fiber amplifier (MOPFA), active phase- compensation, and beam-tilting techniques to demonstrate high fill factor coherent beam combining. First, we optimize a single-frequency, linearly polarized MOPFA system with high scalability and flexibility based on compact, high efficiency Yb-doped fiber amplifier chains. Second, we demonstrate high fill factor coherent beam combining of these MOPFA arrays at a 50W level in the far field successfully. Last, the interference matrix of eight element arrays under an opened loop condition is investigated. Scaling the system to higher power can be expected by increasing the power per fiber chain and adding the number of laser channels.
