摘要

我们报告了在光学腔中使用非简并的四波混合在真空波动级附近的功率电平上观察到压缩光噪声。(1-4)在腔共振处的光使用平衡纯差检测器，其中一部分泵浦光束作为本振。(5)噪声功率在特定相位被放大a倍，在相移90°时被衰减1/ a。这是压缩光的基本识别特性。

Observation of Squeezed Light in an Optical Cavity

We report the observation of squeezed light noise at power levels near the vacuum fluctuation level using nondegenerate four-wave-mixinq in an optical cavity.(1-4) The light at cavity resonances is observed using a balanced homodyne detector with a portion of the pump beam serving as a local oscillator.(5) The noise power is amplified by a factor A at a particular phase and attenuated by 1/A at a phase shift of 90°. This is a basic identifying characteristic of squeezed 1ight.
