Phase Locking of Sixteen Laser Beams Using Stochastic Parallel Gradient Descent Algorithm
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.
