摘要
分析了单色泵浦光子流和量子真空噪声对非线性晶体的综合作用,从泵浦光与非线性晶体的相互作用过程解释了自发参量下转换光场(SPDC光场)的产生根源,推导了SPDC双光子态的数学表达式,并给出其几率解释.
The comprehensive action of monochromatic flux of pumping photons and quantum vacuum noise on nonlinear crystals without symmetric center is analyzed. The generating origin of the light field with SPDC expounded with the interaction of the pumping photons with the nonlinear crystals. The mathematic expression of two-photon state with SPDC is derived and its probability explanation is given.
