摘要
根据量子力学的态叠加原理,构造了由强度不相等的两个多模复共轭相干态|{z_j^((a)*)}〉_q和|{z_j^((b)*)}〉_q,这两者的线性叠加所组成的非对称两态叠加多模叠加态光场|Ψ〉_q。利用多模压缩态理论,研究了态|Ψ〉_q的等幂次N次方H压缩特性,结果表明:当满足一定的相位条件时,无论腔模总数q与压缩次数N两者之积qN是奇数还是偶数,态|Ψ〉_q的两个正交相位分量总可分别呈现出等幂次N次方H压缩效应。
Based on the superposition theory in the quantum mechanics, the multi-mode superposition light field state is constituted by two nonsymrnetry multi-mode coherent states and which intensities are unequal. By using higer-order squeezing theory in multi-mode states, the equal-power Nth power H-squeezing properties of the is studied. It is found that when the certain phase conditions are satisfied,the two quardrature phase components in the present alternately equal-power Nth power H-squeezing effect which changes periodically, whether qN which is the product of cavity-mode total number q and squeezing -order N is odd number or even number.
