摘要

超低膨胀腔在激光稳定中起着至关重要的作用，在离子钟中也是必不可少的。提出了一种用超低膨胀材料间隔片测量法布里-珀罗腔(FPC)反射镜之间绝对距离和温度变化引起的距离变化的方法。FPC被放置在温度稳定的真空不锈钢室中。

Long-term temperature stabilized measurement of ultra-low expansion Fabry-Perot cavity

The ultra low expansion cavities play a crucial role in laser stabilization, and they are essential in ion clocks. We present a method to measure absolute distance between mirrors of Fabry-Perot cavity (FPC) with a spacer from an ultra low expansion material and the changes of the distance caused by temperature variation with femtometer resolution. The FPC was placed into a temperature-stabilized vacuum stainless steel chamber.
