摘要: A theoretical method is developed to treat wideband pulsed squeezing in a traveling-wave parametric amplifier with group-velocity dispersion. Classical stochastic wave equations that are fully equivalent operator of motion and solved numerically. It found occurs over the entire phase-matching bandwidth, although degree decreases when pump-pulse duration shorter than inverse this bandwidth.
