【Abstract】 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.更多还原
