A Experimental Study of Routes of Chaos in a Molecular Beam Maser Oscillator.
Available from UMI in association with The British Library. A study has been made of non-linear phenomena in a molecular beam oscillator operated with an intense pulsed supersonic molecular beam. This includes measurements of the time of silence as well as the self-induced Rabi oscillation following the overfulfilment of the oscillation condition. Up to four cycles of amplitude modulation at the high frequency of 15kHz has been observed for the first time. On account of the strong oscillation made possible with this system, novel nonlinear phenomena on the route to oscillation chaos become observable when the maser is operated in a weak magnetic field which produces a small Zeeman splitting of the maser emission line. The oscillation amplitude time variation includes the following forms: quasiperiodic, period doubling and non-periodic. These phenomena are discussed in terms of the model provided by Oraevskii's strange attractor maser theory.
