Passive coherent combining of two high-brightness tapered laser diodes in a Michelson external cavity
Abstract
We propose a newCBC architecture for the passive phase-locking of a diode laser array that is designed to ensure a stable high-power operation and a high electrical-to-optical efficiency. It uses a common laser external cavity on the back side of the emitters for phase locking, while coherent beam superposition of the phase-locked beams is realized on the front side.
