We have investigated the stability properties of two and three element laser arrays that are nearest neighbor coupled. A novel form of generalized synchronization has been discovered, where the outer elements of the three laser linear array are synchronized identically, but the middle one is not synchronized with the outter ones. Experiments on fiber ring lasers have lead to a model that employs delay equations coupled to a differential equation to describe the fast nanosecond dynamics of the polarized light output from these lasers. Four wave mixing of light beams at detuned frequencies has been studied both experimentally and theoretically and a uniques set of measurements has been analyzed. Phase fluctuations of the light play an important role in the propagation of the sidebands through the fiber. The first experiments on optical communication with chaotic fiber lasers have been performed.
