Generation of strongly chaotic beats

The letter proposes a procedure for generation of strongly chaotic beats that have been hardly obtainable hitherto. The beats are generated in a nonlinear optical system governing second-harmonic generation of light. The proposition is based on the concept of an optical coupler but can be easily adopted to other nonlinear systems and Chua's circuits.Comment: 10 pages, 4 figures, accepted for publication in Int.J.Bif.Chao
