摘　　要：目的研究任意多态叠加多模叠加态光场的广义非线性等幂次差压缩特性,从理论上导出该光场呈现高次差压缩的条件。方法根据量子力学中的态叠加原理并利用多模压缩态理论,推出广义电场和广义磁场分量的量子涨落情况。结果给出了任意多态叠加多模叠加态光场的广义非线性等幂次高次差压缩的一般表达式。结论现有的研究报道是所得普遍性结果在各种不同条件下的特例。Aim To find out the squeezing conditions theoretically and the properties of equal-power nonlinear difference squeezing in muhimode radiation field with any amount of states superposing studied. Methods By utilizing the principle of superposing states in quantum mechanics and the gene.ral theory of muhimode squeezing states, the quantum fluctuation of the general both electronic and magnetic field component were figured. Results The general expressions of equal-power high-power nonlinear difference squeezing in the muhimode state light field with any amount of states superposing was given. Conclusion It was found that all of the formerly studied muhimode superposition states are the special examples under the different conditions.
