PHASE-LOCKED LASER ARRAY ABSTRACT OF THE DISCLOSURE A phase-locked laser, array comprises a body of semiconductor material having structure for defining a plura- lity of substantially parallel lasing zones which are spaced an effective distance apart so that the modes of the adjacent lasing zones are phase-locked to one another. One of the array electrodes comprises a plurality of electrical contacts to the body between the lasing zones. These contacts provide an enhanced current density profile and thus an increase in the gain in the regions between the lasing zones so that zero degree phase-shift operation between adjacent lasing zones is achievable.
