Self-pulsing behaviour in a mesomaser

The dynamics of a mesoscopic system of two-level Rydberg atoms, in resonant interaction with a microwave cavity mode and a coherent injected signal, is described in terms of Maxwell-Bloch equations with atomic propagation.

Description
Summary:The dynamics of a mesoscopic system of two-level Rydberg atoms, in resonant interaction with a microwave cavity mode and a coherent injected signal, is described in terms of Maxwell-Bloch equations with atomic propagation. When the system operates as an absorber, atomic cooperation can induce multistability as well as temporal instability and self-pulsing, quite differently from standard absorptive optical bistability. The self-pulsing behaviour is discussed in detail. At the instability boundaries the numerically calculated values of the oscillation frequency turn out to be in excellent agreement with those predicted by the linear stability analysis.
