Abstract
The action of the so-called green noise (the noise whose spectral density is zero at zero frequency) oil the parametric Synchronization in a ring laser and in a phase-locked loop system is analyzed. The Krylov-Bogolyubov averaging method is used for the theoretical study. The numerical simulation of the harmonic and subharmonic modes is performed on the basis of a one-step collocation algorithm. It is demonstrated that green noise significantly stabilizes a system in comparison to white noise and maintains the zones of parametric synchronization even at relatively high frequencies of harmonics and subharmonics of the input signal.File in questo prodotto:
