参量放大及迭加态中场的振幅立方压缩

Amplitude--Cubed Squeezing of Fields In Parametric Amplification and Superposition States

本文研究辐射场的振幅立方压缩效应,讨论了能够产生振幅立方压缩的简并参量放大过程,证明了振幅立方压缩也是一种非经典效应,并通过对一类迭加态光场存在振幅立方压缩的条件的研究,指出振幅立方压缩与通常的二阶压缩以及由Hong和Mandel提出的高阶压缩并不等价。

In this paper the amplitude--squeezing is studied and shown to be a nonclassicaleffect. Degenerate parametric amplification process in which the amplitude-cubedsqueezing can be produced is discussed. A type of superposition states optical fieldswhich can exhibit amplitude--cubed squeezing is studied and it is shown that thishigher-order squeezing is not equivalent to common second-order squeezing and thehigher--order squeezing defined recently by Hong and Mandel.
