摘要
研究了相干态光场和原子的相互作用,在这一过程中光场展现出反聚束和光子亚泊松分布现象.着重分析了相干态光场在此作用过程中所展现出的光子统计特性.可以看出相干态光场的平均光子数和多光子跃迁对光场非经典性质有强烈地影响.
Interaction of coherent field with atom are studied. We find that the field may exhibition photon antibunching and photon sub-poissonian distribution. We also study the photon statistic properties of coherent field in the process. It can be find that average photon number of coherent field and nonlinear coupling of Kerr medium have intense influence on the non-classical properties.
