【 摘 要 】

A numerical model of a coherent beam composed of a two-dimensional array of laser beams was developed; the model enables analysis of random phase mismatch in the combined system, as well as analysis of the influence of atmospheric turbulence. The negative impact of the beam profile, filling factor, and average inter-beam coherence was analyzed. This analysis reveals parametric ranges in which performance metrics decrease by less than 20% of their peak values. Ensuring partial coherence was the most challenging task.
