摘　　要：构造了由多模相干态、多模复共轭相干态和它的相反态线性叠加所组成的三态叠加多模叠加态光场,利用多模压缩态理论,研究了其广义磁场的等幂次N次方H压缩特性。结果发现,当压缩次数为偶数时,只要各模的初始相位,态间的初始相位差以及受各模初始相位调制的平均光子数之和分别在一定的闭区间内连续变化时,则此态的广义磁场分量(即第一正交相位分量)总可以呈现出周期性变化的广义非线性等幂次偶数次H压缩效应。Three - state superposition multimode superposition state light - field is constructed by the linear superposition of multimode coherent state, multimode complex conjugate coherent state and its contrary state. Through multimode squeezing theory, the characteristics of generalized magnetic field equal power N - th power H - squeezing are studied. It is found that, when the squeezed power number is even, and when the initial phases of each mode, the initial phase differences between states, and the sum of the average number for initial phase modulation of each state change continuously between certain closed intervals, then the generalized magnetic field component can always present the effect of periodically changing and generalized non- linear equal- power even - number - power H - squeezing.
