Abstract: A novel mutual injection phase-locking fiber laser combining technique is proposed, based on a corner-cube and a beam splitter with reflectivity of 50% at 45°, and the mutual injection phase-locking principle is introduced. Mutual injection phase-locking of two individual double clad fiber lasers is experimentally realized, steady interference stripes with high contrast ratio(about 0.57)are observed and more than 10W output power is obtained, which indicates that the power combining efficiency is 76%. Successful attempts of phase lock show that this mutual injection-locking method is a promising technology in the field of fiber laser coherent and the output power can be further scaled.
