Abstract

We present what we believe to be a new approach for active phasing a mutual injection-locked fiber laser array. The combined advantage of active phasing and mutual injection provides a robust performance in the practical turbulent environment and high tolerance on the requirement on the laser linewidth. A proof-of-concept experiment is performed by active phasing a mutually coupled laser array, and a fringe contrast of more than 79% of the in-phase intensity pattern at the receiving plane is obtained.
