本文在实验上测量了运转于阈值以上的双共振光学参量振荡器所产生的孪生光束在时域内的关联特性.在分析腔带宽对孪生光束强度量子关联影响的基础上,通过时域内的数据采集,运用改变孪生光束其中一臂的时间延时的方法来考察时域内孪生光束关联度的变化.在实验上给出了孪生光束关联度大小随时间变化的结果.

This paper discusses a time-domain measurement scheme of quantum correlation of twin beams generated by a non-degenerated optical parametric oscillator operating above threshold. By using data-acquire technique we analyzed quantum correlation of twin beams in timedomain. An experimental demonstration about the change of quantum correlation of twin beams along with the time is given in this paper.
