|
摘要
分析并测量了405nm泵浦光产生的Ⅱ类SPDC纠缠点附近小范围内光子通量的空间分布,辅助Ⅱ类SPDC纠缠源调节,从而有助于减少教学实验所需时间,增强学生对纠缠点空间定位理论的理解,有助于学生更好地开展实验学习.并为对光场进行详细分析以建立程序自动调节纠缠源提供了基础和可能.
The photon flux distribution near the entangled photons in type-ⅡSPDC was investigated to help the adjustment of entangled twin-photon source.The result of this article further decreases the time needed for this teaching experiment and enhances students' understanding for locating entangled photons.And the result provides basis for the precise mapping of type-Ⅱ SPDC and automatically adjusting program for entangled twin-photon source.
