摘要:

本文讨论了在相干光场中产生光场时,有无耦合函数泵浦涨落的参量放大器。泵浦波动被假定为正态分布与时间相关的方差。讨论了光子的反聚束效应和相互关系对光子分布、模间关联和阶乘矩的影响。的初始平均光子数的某些值的光子反聚束的可能增强示出和讨论。我们还证明了新的态(称为修正的压缩真空态,甚至热态)可以从这样的相互作用中产生。此外,我们已经证明,总光子数分布可以表现出崩溃和复苏的光子数域有点类似于那些已知的Jaynes-Cummings模型。

英文摘要:

The parametric amplifier with and without the pumping fluctuations of coupling function is considered when the fields are initially prepared in coherent light. The pumping fluctuations are assumed to be normally distributed with time-dependent variance. The effects of antibunching and anticorrelation of photons on the photon distribution, correlation between modes and factorial moments are demonstrated. A possible enhancement of photon antibunching for certain values of initial mean photon numbers is shown and discussed. We have shown also that new states (called modified squeezed vacuum states or even thermal states) can be generated from such an interaction. Further, we have demonstrated that the sum photon-number distribution can exhibit collapses and revivals in the photon-number domain somewhat similar to those known in the Jaynes-Cummings model.
