In this paper we present the results of analytical and numerical studies into synchronization of a large number of optically coupled resonators with random detuning of eigenfrequencies. We consider the `nearest-neighbor' coupling model with allowance made for gain saturation. Assuming that the coupling coefficient has zero imaginary part, the problem of steady-state phase distribution over the aperture of the two-dimensional array reduces to the problem of temperature distribution in a 2-D medium at the presence of heat sources and coolers with random powers. It is shown that the steady-state phase distribution over the aperture has the domain-like form. Phases in adjacent domains differ by values of the order of (pi) . Combining the scheme with nearest-neighbor coupling and external signal injection, we can easily attain synchronous lasing from large arrays.
