摘要
In this paper, we report the passive phase locking of a four fiber lasers array by mutual injection locking. The four fiber lasers are mutually injected by four 5/5/90 couplers. Through mutual injection locking, good coherence has been obtained in the far field. The four fiber lasers can operate at the same wavelength with a stable output power. This scheme is quite easy to implement and can be extended to combine more beams. (C) 2009 Elsevier Inc. All rights reserved.
