摘要：
Coherent beam combination of up to sixteen fiber laser beams using stochastic parallel gradient descent (SPGD) algorithm is demonstrated. The phase control is implemented by running SPGD algorithm on a digital signal processor (DSP). The combined laser power of the system in close-loop can be improved 12 times compared with the power in open-loop.
