Compact all-fiber polarization-maintained single frequency fiber amplifier chains are developed and four fiber amplifiers are arranged to 2 × 2 laser array with a fill factor of 70% in the near-field. Active phase control is implemented by a digital signal processor (DSP) based SPGD controller. The fringe visibility of the coherent combined beam profile is as high as 81% when the system is closed-loop controlled despite perturbations of the environment. Article Outline Introduction Experimental setup Results and discussion Conclusions Acknowledgements References Research Research highlights Four polarization-maintained single frequency fiber amplifier chains are optimized. ? Coherent beam combining of 137W 2×2 fiber amplifier array is demonstrated. ? Fill factor as high as 70% is realized in coherent beam combining.
