ABSTRACT:
A phase-locked linear laser array has an output array in which equispaced optical gain elements are formed along a semiconductor bar and a control laser array having equispaced laser elements in close coupling with the output array. The output array elements, having twice the spacing of the control array elements, are aligned with alternating elements of the control array. The tendency of the control array lasers to operate with 180.degree. optical phase difference between adjacent lasers causes every other laser to be in-phase and thus adjacent elements of the output array are also in-phase.
