Brighter far-field pattern of a phase-locked Nd:YAG microchip laser array was obtained by the Talbot effect in a three-mirror cavity. The laterally coupled Nd:YAG microchip laser array produced a pair of spots with sharper peaks with an angular separation of λ/d in its far-field, where d is the distance between the adjacent sources, indicating an out-of-phase spatial mode coupling was improved. The far-field spot size is reduced by a factor of 9.3 compared with that obtained by incoherent pile of the individual microchip laser outputs. We demonstrated that the far-field pattern is improved by enhancing the self-imaging with side mirrors which make the array source disguise as infinity. A mode selecting slit placed right after the crystal is also effective to stabilize the out-of-phase mode.
