Abstract:The coherent beam addition of pulsed fiber lasers is an effective way to improve the average power and the peak pulse power. We demonstrate a new architecture based on mutual injection and phase modulation to generate synchronous pulsed fiber lasers. Firstly, we realize the synchronization of the pulses of three fiber lasers using this technique. Secondly, coherent addition of three synchronous pulsed fiber lasers is obtained. Experimental results show that the three fiber lasers are phase locked and have good temporal and spatial coherence under mutual injection locking. This method can be extended to combine more beams.
