-10- PHASE-LOCKED LASER ARRAY WITH VARYING ELECTRICAL CURRENT DISTRIBUTION ABSTRACT OF THE DISCLOSURE A phase locked laser array comprises a body of semiconductor material which includes structure for defining a plurality of substantially parallel lasing zones which are uniformly spaced an effective distance apart so that the propagating modes of the adjacent lasing zones are phase- locked to one another. One of the array electrodes comprises a plurality of electrical contacts extending between the end faces and having lateral unequal widths and center-to-center spacings. These contacts provide a laterally varying electrical current distribution across the plurality of lasing zones.
