摘    要:利用新近提出的多模辐射场的广义非线性等阶高阶压缩理论,对多模复共轭奇、偶相干态光场的N次方Y压缩与N次方H压缩特性进行了详细研究.结果发现:①多模复共轭奇相干态光场,压缩阶数N为偶数时,只存在N-Y最小测不准态;而当腔模总数q与压缩阶数的乘积q·N为偶数时,只存在N-H最小测不准态;此外,无论N及q·N为何值,不呈现N次方Y压缩与N次方H压缩效应.②多模复共轭偶相干态光场在一定条件下可呈现出周期性变化的任意阶的N次方Y压缩与N次方H压缩效应.③多模偶相干态光场与多模复共轭偶相干态光场两者的压缩效果和压缩特性完全相同,这种现象称为“压缩简并”.

关 键 词:多模复共轭奇相干态  多模复共轭偶相干态  N-Y最小测不准态  N-H最小测不准态  N次方Y压缩  N次方H压缩  压缩简并

Abstract:In this paper,the properties of N-th power Y-squeezing and N-th power H-squeezing of the multi-mode odd and even-coherent state light field is studied in detail,that is based upon utilizing the theory of generalized nonlinear equal-order and unequalled-order higher-order squeezing of multi-mode radiative light field which is proposed by Yang Zhiyong and Hou Xun recently.It is found that,①When N,the number of squeezing-order,is an even-number,the multi-mode complex conjugation odd coherent state light field only present N-Y minimum uncertainty state;When q·N,the products of cavity modes number and squeezing-order number,is an even-number multi-mode complex conjugation odd coherents state present N-H minimum uncertainty state only;and when N and q·N are any numbers,multi-mode complex conjugation odd coherent state does not present the properties of N-th power Y-squeezing and N-th power H-squeezing.②The multi-mode complex conjugation even-coherent state light field,under some certain conditions,can present any order N-th power Y-squeezing and N-th power H-squeezing which changes periodically.③Both the squeezing result and squeezing characteristic between multi-mode complex conjugation even-coherent state light field and multi-mode even-coherent state light field are the same completely,this phenomenon is so called ‘squeezing degenerate’.
