摘要：

使用反馈回路，可以减少环路内场的一个正交中的波动，而不会增加另一个正交中的波动。这种效应已经知道很久了，最近被称为"挤压“[B. C. Buchler等人，Optics Letters { \bf 24}，259（1999）]，这与自由场的“挤压”相反，在自由场中共轭波动增加。本文提出了压缩的一般理论，包括两个求积函数的同时压缩和同时压缩。我表明，一个二能级原子耦合到环内光的感觉波动的影响，理论计算。在光的理想极限中，光在一个正交方向上压缩，在另一个正交方向上压缩，原子衰变可以被完全抑制。

英文摘要：

Using a feedback loop it is possible to reduce the fluctuations in one quadrature of an in-loop field without increasing the fluctuations in the other. This effect has been known for a long time, and has recently been called ``squashing'' [B.C. Buchler et al., Optics Letters {\bf 24}, 259 (1999)], as opposed to the ``squeezing'' of a free field in which the conjugate fluctuations are increased. In this paper I present a general theory of squashing, including simultaneous squashing of both quadratures and simultaneous squeezing and squashing. I show that a two-level atom coupled to the in-loop light feels the effect of the fluctuations as calculated by the theory. In the ideal limit of light squeezed in one quadrature and squashed in the other, the atomic decay can be completely suppressed.
