Abstract

Numerical simulation is presented to analyze the influence of nonuniform polarization states on a phase locked laser beams array. Beam propagation factor (BPF) is used to evaluate the quality of the combined beam. For a beams array with different polarization states, SPGD algorithm can be used for modulating the phases of the beams to get higher energy concentration degree at far field. The numerical simulation shows that the BPF of a beams array with nonuniform polarization states is smaller than an ideal beams array with uniform polarization states. The average of BPF value decreases with the increase of array number. SPGD algorithm corrects the polarized component that contains more energy as priority.
