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,本文分别以基模圆高斯激光束、厄米-圆高斯激光束、拉盖尔-圆高斯激光束、基模椭圆高斯激光束和厄米-椭圆高斯激光束为例,通过大量的数值计算并借助计算机绘图,利用多模压缩态理论,详细研究了激光场经典强度和经典振幅等在空间呈现的圆高斯分布和椭圆高斯分布特征对三态叠加多模叠加态光场的广义非线性等幂次N次方Y压缩的影响。Constructs the three- state superposition multimode superposition state light field that is composed of multimode coherent state, multimode complex conjugated coherent state and its opoosite state, which are superposed linearly. This paper takes Gaussian laser beam, Hermitian - Gaussian laser beam, Laguerre- Gaussian laser beam, ground mode elliptical - Gaussian laser beam and Hermitian - ellptical Gaussian laser beam as examples seperately, through large data computation and computer graphing, and with the multimode squeezed state theory, studys in detail how the spatial round Gaussian distribution and ellipse distribution of classical intensity,classical amplitude and classical phase affect the generalized nonlinear equal - power N - th power Y - squeezing of the three- state superposition multimode superposition light field.
