摘　　要：根据量子力学中态的线性叠加原理 ,构造了由多模复共轭相干态 |{Z j}〉q(j=1,2 ,……q)、多模复共轭虚相干态 |{iZ j}〉q 和多模真空态 |{ 0 j}〉q 的线性叠加组成的第Ⅲ类三态叠加多模叠加态光场 |ψ(3)3 〉q 利用多模压缩态理论 ,研究了态 |ψ(3)3 〉q 广义磁场分量 (即第一正交相位分量 )的广义非线性等幂次高次和压缩特性 结果发现 :当腔模总数q与压缩次数N之积qN取偶数时 ,态 |ψ(3)3 〉q 广义磁场分量在一定条件下可分别呈现出周期性变化的、广义非线性等幂次奇数模—偶数次。It is studied that the effects of generalized nonlinear equal-powor higher-power sum squeezing of generalized magnetic field component in the third kind of the three state superpositions multimode superposition state light field |ψ (3) 3> qwhich is composed of the multimode complex conjugation coherent state |{z* j}> q, the multimode complex conjugation imaginary coherent state |{iz* j}> q and the multimode vaccum state|{0 j}> q. The result show that the state |ψ (3) 3> q is a new type of three state superposition multimode nonclassical light field. If qN, the products of cavity-mode-number q and the squeezing-power-number N, is an even number only, and under some certain conditions, the generalized magnetic component (or the first perpendicular phase component) in the state |ψ (3) 3> q can always present generalized nonlinear equal-power odd-numer-mode with even-number-power, even-number-mode with odd-number-power, and even-number-mode with even-number-power higher-power sum squeezing effects respectively, which changes periodically.
