【摘要】 本文根据Zhang等人定义的高阶压缩,研究了单模光场态|ψ_M＞=α|0＞+β|m＞(m=1,2,…)的高阶压缩特性.结果表明,这种光场态不但存在振幅m次方压缩,而且当m为偶数量还存在振幅m/2次方压缩.因此,这种高阶压缩与Hong和Mandel定义的高阶压缩是相互独立的,在此之前,文献[1]所讨论的只是我们所得普遍性结论的一个N=2的特例.更多还原

【Abstract】 According to the definition of higher -order squeezing given by Zhang et al., the properties of the higher-order squeezing of a single mode light field states |m> = α|0>+β|m> (m=l, 2, are studied in this paper. The results show that it exhibits not only the amplitude mth- power squeezing, but also the amplitude m/2th-power squeezing when m is even integral. Therefore, this kind of higher-order squeezing is independet of the higher-order squeezing defined by Hong and Mandel. The result given by the reference [1] is only a special instance (N = 2) of the general conclusion of ours.更多还原
