| 摘 要： | 本文利用新近建立的多模压缩态理论,详细研究了一种新型的多模复共轭虚偶相干态光场|Ψi,e*(2)>q的广义非线性等阶N次方Y压缩与等阶N次方H压缩特性.结果发现:1)当压缩阶数N为奇数时,态Ψi,e*(2)>q在一定条件下总可呈现出周期性变化的、任意阶的等阶N次方Y压缩效应;当腔模总数q与压缩阶数N两者之乘积q·N为奇数时,则在一定条件下态|Ψi,e*(2)>q又可呈现出周期性变化的、任意阶的等阶N次方H压缩效应.2)态|Ψi,e*(2)>q与多模偶相干态光场|Ψi,e*(2)>q与多模虚偶相干态光场|Ψi,e(2)>q的压缩幅度、压缩条件和压缩特征等完全相同.这一结果再次从理论上证实了多模压缩光中的确存在着“相反压缩”和“压缩简并”这两类新的物理现象. |

| Abstract: | In this paper,the properties of both generalized nonlinear equal-order N-th power Y-squeezing and generalized nonlinear equal-order N-th power H-squeezing in a new type of multimode complex conjugation imaginary-even coherentstate lightfield|Ψi,e*(2)>qare sudied in detail,by utilizing the theory of multimode squeezed state constructed by Yang Zhiyong and Hou Xun and published in Acta Photonica Sinica recently.Itis found that 1).If the squeezed order number N is an odd number,the state|Ψi,e*(2)>qmentioned above can always presentany ordergeneralized nonlinearequal-order N-th power Y-squeezing that changes periodically under some certain conditions;and if q ·N,the products of cavity-mode number q and the squeezed order number N,is an odd number,the state |Ψi,e*(2)>q mentioned can also display any ordergeneralized nonlinearequal-order N-th power H-squeezing thatchanges periodically too.2) The squeezing conditions and the squeezing featuresof both equal-order N-th power Y-squeezing and equal-order N-th power H-squeezing of the multimode complex conjugation imaginary-even coherent state|Ψi,e*(2)>q are just contrary to that of the multimode even-coherentstate|Ψe>q,and to thatof the multimode complex-conjugation even-coherentstate |Ψi,e*(2)>q,butjustthe same as thatof the multimode imaginary-even coherentstate|Ψi,e(2)>q.So the two kinds of new physical phenomena,the so-called“contrary squeezing”and“degenerat squeezing”,are further improved by the results mentioned above in this paper. |
