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.
