Phase filtering of the inphase mode of a linear laser array in the Talbot resonator

A technique for phase filtering of the inphase collective mode of a laser array in the Talbot resonator is developed. This technique is based on the formation of the phase distribution of the inphase mode field of the linear array with the finite number of channels close to that of the field of the infinite periodic structure. A simple scheme of the phase corrector, providing the increase in the selectivity of the inphase mode of the laser array in the Talbot resonator, is proposed. It is shown that the width of the principal maximum of the far-field intensity does not increase during the phase filtering.
