UNIQUENESS OF THE CHAOTIC ATTRACTOR OF A SINGLE-MODE LASER

Measurements on an optically pumped NH, single-mode laser show, three different types of chaotic dynamics, Lorentz-type spiral chaos, period-doubling chaos,and type-III intermittency. Analysis of the measurements shows that the peak-intensity return maps of these three, types of dynamics have the same shape, indicating that a unique attractor exists for the laser whose topological structure is independent of laser parameters.
