Abstract

A new passive technique approach to phase lock a laser array is proposed and analyzed. It improves the laser combining efficiency with a large number of emitters. Our architecture combines selective coupling based on phase-contrast filter and resonant phase nonlinearity of amplifiers. A numerical study predicts that with 20 fiber lasers the architecture leads to a phase locking efficiency which is twice the value observed up to now in published experiments.
