Passive coherent combining of two tapered laser diodes in an interferometric external cavity (poster)

Abstract : We demonstrate a rear-side phase-locking architecture with two high-brightness diode lasers. This technique is based on the passive phase-locking of emitters in an external cavity on their rear facet, and their coherent combination on the front facet. Two high-brightness high-power tapered laser diodes are coherently combined using a Michelson-based cavity. The combining efficiency is above 80% and results in an output power of 6.5 W in a nearly diffraction-limited beam.
