摘　　要：给出了受Ｍｉｌｂｕｒｎ方程控制的双模双光子Ｊａｙｎｅｓ－Ｃｕｍｍｉｎｇｓ模型的精确解。由于内在消相干性的存在，原子反转以及双模光场的平均光子数随时间演化而衰减，同时光子的反聚束效应及双模光场的相干性也受到内在消相干性的影响。We give the exact solution of the two mode two photon Jaynes Cummings model governed by the Milburn equation in the initial condition that two level atom is in exited state and the two mode field is in the pair coherent state. Due to the existence of the intrinsic decoherence, the atomic inversion and the mean numbers of photons of two modes decay with time evolution. We also dicuss the photon antribunching propertics in the modes and their degree of the cross corrclation.
