【Abstract】 The first kind of the three state superposition multimode superposition light field ｜ψ (3) 1〉 q is constructed that is made of multimode coherent state light field ｜｛Z j｝〉 q 、multimode vaccum state light field ｜｛0 j｝〉 q and contrary state ｜｛ Z j｝〉 q of multimode coherent state and that is based upon the linear superposition principle of quantum state in quantum mechanics in this paper. Then the multimode squeezed state theory is utilized to study the properties of equal power higher power sum squeezing of generalized magnetic field component in the state ｜ψ (3) 1〉 q in detail. It is found that the state ｜ψ (3) 1〉 q is a new type of three state superposition multimode nonclassical light field, while some certain conditions are satisfied bythe initial phase sum qj=1φ j of each mode in the state ｜ψ (3) 1〉 q , and while the initial phase difference (θ (R) pq θ (0) 0q )、(θ (R) nq θ (0) 0q ) and (θ (R) pq θ (R) nq ) between any two states in the state ｜ψ (3) 1〉 q change continuously within their own fixed and closed regions respectively, the generalized magnetic field component (or the first perpendicular phase component) of the state ｜ψ (3) 1〉 q can always display the generalized nonlinear equal power odd number mode with even number power, even number mode with odd number power, even number mode with even number power, and odd number mode with odd number power higher power sum squeezing, respectively, which changes periodically.更多还原
