The purpose of this paper is to deduce an analytical expression for the violation of Bell’s inequality by quantum theory and plane trigonometry, and expound the violation and maximal violation of the first, second type Bell’s inequality in detail. Further, we find out the sufficient conditions for the region in which Bell’s inequalities are violated.

In this paper, we derive the bright and dark photon number states for spatial interference of two or more light beams and succeed in the explanation of Young's interference experiment, and also achieve a better comprehension of the well known comment of Dirac "each photon only interferences with itself". From the fully quantum point of view, the origin of the interference fringes consists in the mode transformation and the detection of double-slit states.

本文应用噪声源的量子理论,分析了一个腔内同时含增益介质及非线性介质的系统在外界非相干光泵浦下输出压缩态光的可能性.结果表明,当系统稳定运转后,出射场有较高的强度,而且电场正交分量之一的起伏被压缩到标准量子限之下.

本文利用多原子系统的再耦合波函数,求出双原子系统的二阶相关函数.通过数值计算,讨论了原子间的受激辐射,原子的纵横弛豫对间I_1、I_2和频率失谐等因素对共振荧光反聚束效应的影响.在T_1>>T_2时,反聚束效应会减小.

本文从实验上,用窄频带和宽频带激光,在无预脉冲和有预脉冲两种情况下,辐照平面Al靶.在垂直入射激光方向观察到高光谱分辨(～0.2?)和空间分辨(～2μm)的二次谐波空间分辨谱.通过分析各种现象,基本上证明了在垂直入射激光方向的二次谐波辐射是由激光与等离子体细丝相互作用所引起的,而不是由平面波与等离子体相互作用引起的,理论和实验基本一致.
