【摘要】 本文研究了一“V”型三能级原于在双模相干光场作用下总偶极算符的演化规律。结果表明，在这种情况下存在偶极压缩效应，它明显受失调量、平均光子数的影响，其偶极演化规律比二能级情况复杂．更多还原

【Abstract】 In this paper,the evolution of the dipole squeezing for a "V" type three-level atom driven by the two-mode coherent state field has been investigated. It is shown that dipole squeezing can be exhibited in the condition and is clearly influenced by the detuning and mean photon numbers,and that the three- level atom is more complicated than thetwo-level atom for the time evolution of the dipole squeezing.更多还原
