摘要
本文研究了单模光场态 ψ=α 0>+β m>(m>2)的高阶压缩,发现当m为偶数时,该态除了不存在二阶压缩外,任意高阶压缩都存在,且高阶压缩并不与反聚束同时出现,由此我们得到一个结论:高阶压缩是独立于二阶压缩与反聚束效应的又一光场非经典效应。
In this paper, the higher-order squeezing of a single mode light field state
is studied. When m is even integral,we find that it exhibits arbitary higher-order squeezing except second order squeezing. But the higher-order squeezing and antibunchinf; do not appear simultaneously- Thus, we come to a conclusion that higher-order squeezing is a new nonclassicl effect of light field which is independent of second order squeezing and antibunching.
