摘　　要：双波长外腔共振是提高和频转换效率的有效手段,然而基于Boyd-Kleinman(BK)理论,和频效率除了受基频光功率密度影响外,主要受BK因子限制。本文通过分析BK因子随腔结构参数的变化关系,给出基于外腔频率转换过程中BK因子优化的一般方案,从而为搭建相关实验提供必要的理论基础。The properties of entanglement evolution between field and two atoms in Gaussian coupling Tavis-Cummings model in the multi-photon transition process are studied on the quantum theory.The influence on the properties of entanglement evolution between field and two atoms from atomic motion,the mean photon number in initial states of the light field,number of transition photons in the multi-photon transition process are discussed.The results show that the variation of atomic motion changes the time for the effective action to the evolution of field entropy.Initial states of the light field affect the evolution period to field entropy.With the increasing of the number of transition photons,the oscillation frequency and the mean degree of entanglement between field and atoms become larger.
