A classical, stochastic, coupled-oscillator model for the emergence of partial coherence in arrays of vertical cavity surface emitting lasers is presented. The spectra of the uncoupled lasers determine the second order coherence properties of the coupled system. Predictions of the resultant radiation and interference patterns are verified experimentally.
