摘　　要：推导了非线性光学Ⅱ类参量下转换 (SPDC)产生的孪生光子环方程 ,分析了该共轭环的图象变化 ,讨论了由双光子态产生的一些有意义的特性 ,描述了从晶体射出的孪生光子环的几何光学现象 ,证实了产生高效孪生光子束的条件 .The equation of the twin photon circles produced in nonlinear optical type Ⅱ spontaneous parametric down conversion(SPDC) was derived. The change of image of the conjugate circles was analyzed. The interesting features arising from the form of the two photon state generated in the process were discussed. The geometric optics phenomena of the rings of radiation from the crystal were described. The generation condition of high efficiency beamlike twin photon was demonstrated.
