Bandwidth and stability of the stochastic parallel gradient descent algorithm for phase control in coherent beam combination

The bandwidth and stability limits of the stochastic parallel gradient descent (SPGD) algorithm used for coherent beam combination is investigated by deriving an analytical model for the phase control loop. The analytical model is compared to experiments and numerical simulations using a laboratory...
