Abstract

We define the occurring conditions of Talbot effect for 2D periodic wave field of general configuration. Corresponding distances of self-reproduction are derived by the simple analytical expression. Dynamics model of the collective generation of waveguide laser array with diffraction coupling in an external cavity is offered. On its basis we calculate the thresholds of collective generation, the selectivities of external cavities, and field distribution in far-zone for 2D arrays of square and triangular filling. The effect of array irregularities on the spectrum of collective modes is discussed.
