摘　　要：利用多模压缩态理论 ,研究了多模叠加态光场 ψ(ab)I 〉q的广义非线性等幂次N次方Y压缩特性 .结果发现 ,在一些特定的条件下 ,态 ψ(ab)I 〉q恒处于等幂次N Y最小测不准态 ,而不呈现等幂次N次方Y压缩效应 .可见 。The properties of generalized nonlinear equal power N th power Y sqeezing on multimode superposition state light field ψ (ab) I> q are studied,by utilizing the theory of multimode squeezed state.It is found that in the some certain condition,the state ψ (ab) I> q can always display the equal power N Y minimum uncertainty state,the state ψ (ab) I> q cant display the equal power N th power Y squeezing effect.It is obvious that in the certain condition multimode superposition state light field composed of asymmetrical coherent state light field always keep down the coherent properties of original light lield.
