Abstract: An investigation was made of diffractive self-reproduction of a periodic wave field of two-dimensional arrays is studied. The conditions are found for the existence of this effect and expressions are derived for the self-reproduction distance. The critical gain increment for a phase-locked mode and the selectivity factor of two-dimensional arrays in Talbot cavities are found. It is shown that the efficiency of an array with a triangular occupancy configuration is higher than the efficiency of a square configuration.
