摘　　要：用改进型有效哈密顿量方法研究简并喇曼过程中辐射场的振幅Ｎ次方压缩。发现如果场初始处于相干态，则它以后不会获得任何次方的压缩。如果场初始处于压缩真空态，则它以后可获Ｎ次方压缩。讨论了场涨落对次幂Ｎ、初场平均光子数ｎ和压缩角ξ的依赖关系。In this paper we study the amplitude Nth-power squeezing of radiation fields in the degenerate Raman process,by using the modified effective Hamiltonian approach recently suggested by us,We found that if the field is initially in a coherent state it will not get squeezing for any Nth-power. If the field is initially in a squeezed vacuum,it may get Nth-power squeezings. The time evolution of the field fluctuation was discussed. Its dependences on power orderN,mean photon number n,and squeezing angleξare analvzed
