Abstract

An attractive technique for increasing the coherent output from semiconductor lasers is to coherently combine the output powers from individual, high-power, single-transverse-mode lasers. A convenient method of achieving coherence between the lasers (without any complex imaging system between the individual lasers) is based on the Talbot effect.¹ In this presentation we report on the first demonstration of high output power from a GaAlAs semiconductor laser array in an external Talbot cavity.
