Abstract : We describe a coherent beam combining architecture based on passive phase-locking of two laser diodes in a Michelson external cavity and their coherent combination. Two ridge lasers have been coherently combined with 90% efficiency. Different active phase-locking schemes have been compared to stabilize the external cavity.
