Paper Abstract

This paper describes a method of enhancing coherence and intensity of a broad-area laser array. An experimental scheme has been proposed to injection lock a single or multiple broad-area high-power lasers in a commercially available 19-laser array driven by a common current source. We experimentally demonstrate both the injection locking of each individual broad-area laser and the simultaneous injection of two broad-area lasers in a 19-laser array using a single-mode laser as the source of injection. The method and required conditions for the simultaneous locking of all 19 lasers have been discovered from the experimental results.
