Abstract

We report on an experimental study of the statistical effects of optical parametric noise on the signal pulses in a synchronously pumped optical parametric oscillator. We measured a signal pulse that grew from the optical parametric noise using a temporal gating system and found that the time required for the signal growth was remarkably scattered, even if the pump pulses were maintained to be constant. The statistical properties of the signal pulses were not affected by the changes in the pump power but were characterized by the optical parametric noise. We examined these statistical properties numerically using nonlinear coupling equations and found that the measured properties could be reproduced using a simple model in which the optical parametric noise had random phase in the frequency domain.
