Synchronization and self-organization in arrays of coupled solid-state lasers - art. no. 053809

We analyze the dynamical properties of arrays of coupled solid-state lasers . The interaction mechanism, valid in the weak-coupling limit is local and described by a complex coupling parameter. We focus our attention on the po ssible synchronization or self-organization properties of the system. Besid es the well-known phase of total order corresponding to complete locking, w eaker collective order is observed and related to the formation of clusters of synchronized units. We discuss, in particular. the roles played in the existence of Such ordered state by the real and by the imaginary parts of t he coupling parameter.
