Noise-induced oscillations in fluctuations of passively mode-locked pulses

摘要

We study the fluctuations of pulses in mode-locked lasers using the statistical light-mode dynamics approach.nThe analysis is based on a decomposition of the laser waveform into three parts: solitary pulse, intracavitynnoise continuum, and local overlap. We discover significant features in the fluctuation dynamics,nbeyond those known in existing theories that disregard the continuum component of the waveform, mostnnotably oscillations in the autocorrelation functions of the pulse power and frequency parameters, and annenhancement of the phase jitter diffusion constant. The theoretical results are corroborated by numericalnsimulations. © 2010 Optical Society of America
