Adaptive Joint Correction of the Piston and Large Tip/Tilt of Beam Combination Using Dynamic Metric Stochastic Parallel Gradient Descent Algorithm

Phase control is paramount for laser beam combination, requiring sequential tip/tilt and piston error correction. The common stochastic parallel gradient descent (SPGD) phase control algorithm using power metrics can't realize the automatic transition from an initial state of spot separation to...
