Experimental Phase Stabilization of a 397-Channel Laser Beam Array Via Image Processing in Dynamic Noise Environment

A phase-locking module is firstly validated for coherent beam combining (CBC) systems of near 400 laser beams in dynamic noise environment. It is based on a 2-dimensional image processing in the phase-locking module to calculate the piston phase of the laser array in the CBC systems. Through the des...
