| Abstract | We introduce a novel (to the best of our knowledge) phasing technique for a coherent laser array. We have accomplished arbitrary phasing in the interval 0-pi. A seven-channel laser array experiment is built for verification. A custom-made beam arraying structure is designed to arrange beamlets into a two-dimensional hexagonal array. In the phase-locking loop, the wavefront sensing is performed interferometrically. An active segmented mirror is used for phasing, and the control signals are generated by the proportional control algorithm. In experiment, all the beamlets have been properly phased, and the experiment of inertia-free beam steering has been accomplished.
