Synchronized chaos of three elements in centered triangular laser arrays

Symmetrical two-dimensional coupled laser arrays in which lasers are placed on the apices and center of an equilateral polygon are proposed for obtain ing a number of synchronized chaotic signals. Numerical simulations for cen tered triangular arrays are conducted and the synchronized chaos of three l asers on the spices (satellite lasers) is observed. The central-satellite c oupling is more important than the satellite-satellite coupling for the syn chronized chaos of all satellite lasers.
