Abstract

This paper describes experimental results on the injection locking of high-power broad-area semiconductor lasers in a commercially available 19-laser array driven by a common current source. Single-frequency optical spectrum and single lobe far-field pattern are observed as a result of injection locking. We discuss the temporal dynamics, the amplification of the injection light, and the phase coherence between the injection-locked lasers, which are key issues in their applications to free-space laser communication.
