Localized synchronization of two coupled solid state lasers

Two coupled lasers exhibiting oscillatory intensities are known to synchronize in phase or out-of-phase and with equal intensities. But a different form of synchronization - called localization - has been discussed recently in the literature of coupled oscillators. Localization means that the two lasers may exhibit different intensities. We show that this phenomenon is possible in a system of two coupled solid state lasers differing only by their detunings. We determine the bifurcation diagram of the localized states and obtain analytical conditions for stable localization.
