Abstract

Phase locking and coherent beam combination of two individual double-clad fiber lasers by a novel extra-cavity mutual injection-locking method based on a corner-cube are proposed and experimentally demonstrated. Steady interference stripes with high contrast ratio(about 81.7%) are observed. The output power of the phase-locked array exceeded 10W and the power combining efficiency is about 80%. No power-restriction optical components are utilized in our phaselocking experiment and the output power can be further up-scaled.
