Paper Abstract

The effective method of phase locking of a laser array with a multibeam intracavity long-range interaction (MBI) in nonlinear media is studied. The conditions under the MBI are determined when the long-range coupling is realized between the lasers (all-to-all type) and when only nearest neighbors interact (close-range coupling). A theoretical examination is given of the influence of the number of lasers, the cavity length detuning, and the coupling coefficients on the threshold gain coefficients and frequency characteristics of phase-locked and phase- unlocked modes of the laser array operation. An effect of parameters of the resonant absorbing medium on phase locking of the laser array is studied, and it is shown that the bandwidth of the synchronization is independent of the number of lasers at the optimal conditions.
