Coherent lasing of two lasers can be achieved passively by intracavity exchange of light between the lasers. Full coherence of the lasers typically implies synchronization in three parameters: frequency, phase, and polarization. Here we investigate a simple laser system in which exchange of light can cause a variety of states: full coherent lasing, only polarization-locked lasing, frequency-locked lasing without phase locking, and independent incoherent lasing.Wedemonstrate these states experimentally with evanescently coupled fiber lasers, and propose a simple model that offers a simple explanation for these intriguing observations.
