Comparison of Lorenz-Like Laser Behavior with the Lorenz Model

In the past we reported about Lorenz-like chaos in optically pumped 14NH3 FIR lasers and about some numerical analysis of its intensity pulse trains. Here, further information is added. From our comparisons of autocorrelation functions, phase portraits, power spectra, correlation dimensions, and entropies between the experimental and numerically established data sets we show that the optically pumped FIR laser in fact can behave like the simple two level Lorenz system in spite of the three molecular energy levels involved in such optically pumped lasers.
