Abstract

We present experimental observations along the roads to chaos of a tuned low-Q solid state spin-flip NMR laser (raser) which, according to our earlier work , should show the universal Feigenbaum scenario under certain conditions. The free running ruby raser is periodically perturbed by modulating one of its physical parameters. For example, one may modulate the pumping magnetization sinusoidally with the angular frequency Ω close to the eigenfrequency of the linearized raser equations, typically f = Ω/2π ≃ 30 Hz.
