Abstract
In this paper, the nonlinear higher-order squeezing theory of two-mode and multi-mode radiative ligh fields, based upon the developing of current squeezing theories, is established by Yang Zhiyong and Hou Xun firstly. So the two kinds of nonlinear higher-order squeezing, both Nth-power Y-squeezing and Nth-power H-squeezing, of two-mode and multi-mode radiative light fields are also defined in new theory. And then a new type of two-mode light field of superposition state |ψ>that linear superposition principle in quantum mechanics is satisfied, is constructed. According to the definition mentioned above, the two kinds of nonlinear higher-order squeezing effects of the state |ψ> are therefore studied in detail. It is found that |ψ> is a new type of nonclassical light field in which there exists eigher any order Nth-power Y-squeezing or any order Nth-power H-squeezing. And under some certain conditions. this two kinds of nonlinear higher-order squeezing effects present the properties of periodic and alternating changes between the naximum squeezing and the minimum squeezing. The definition of Nth power squeezing of single-mode radiative light field amplitude proposed in reference 7 is only the specific example of this paper under the condition of k=1.
